[PATCH v4 0/4] General regulator and pmic uclass improvements
by Svyatoslav Ryhel 04 Oct '23

04 Oct '23

This patchset derives from discussion of TPS65913 bringup and aims to cycle all regulator management inside uclass removing need of any board calls for regulators. My hw setup is Tegra 3 LG Optimus Vu P895 (PMIC is MAX77663) with native spl u-boot build. power: regulator: expand basic reference counter onto all uclass Commit is basically expansion of 4fcba5d ("regulator: implement basic reference counter") onto all regulators. My testing on hw has shown no issues so far with both pmic regulators and fixed regulators. Counting works as expected, dm test is set in test of regulator_set_enable_if_allowed. power: regulator-uclass: perform regulator setup inside uclass All regulators with always-on or boot-on are set to probe after bind which ensures that essential regulators are set. In the post probe regulator autoset is called so that correct regulator state according to device tree is reached. DM test is set by checking regulators data without pre-configuring them manually. --- Changes from v3: - no changes, re-sending Changes from v2: - dropped changes related to pmic (pmic regulator probing on pmic post bind) - regulator uclass changes are dropped to minimum to remain compatibility: - always-on and boot-on check is moved to post bind - regulator_autoset is called on post_probe - adjusted dm tests to pass with this changes Changes from v1: - adapted description of regulator_set_enable - remove uc_pdata->enable_count from post_probe - added tests from counter and regulators post_probe --- Svyatoslav Ryhel (4): power: regulator: expand basic reference counter onto all uclass test: dm: regulator: test counter in set_enable_if_allowed test power: regulator: Perform regulator setup inside uclass test: dm: regulator: provide test of auto setup drivers/power/regulator/regulator-uclass.c | 71 ++++++++++++++++++++-- drivers/power/regulator/regulator_common.c | 22 ------- drivers/power/regulator/regulator_common.h | 21 ------- include/power/regulator.h | 2 + test/dm/regulator.c | 27 +++++++- 5 files changed, 92 insertions(+), 51 deletions(-) -- 2.39.2

[PATCH 0/3] BOOTP/DHCPv4 enhancements
by seanedmond＠linux.microsoft.com 03 Oct '23

03 Oct '23

From: Sean Edmond <seanedmond(a)microsoft.com> In our datacenter application, a single DHCP server is servicing 36000+ clients. Improvements are required to the DHCPv4 retransmission behavior to align with RFC and ensure less pressure is exerted on the server: - retransmission backoff interval maximum is configurable (environment variable bootpretransmitperiodmax) - initial retransmission backoff interval is configurable (environment variable bootpretransmitperiodinit) - transaction ID is kept the same for each BOOTP/DHCPv4 request (not recreated on each retry) For our application we'll use: - bootpretransmitperiodmax=16000 - bootpretransmitperiodinit=2000 A new configuration BOOTP_RANDOM_XID has been added to enable a randomized BOOTP/DHCPv4 transaction ID. Add functionality for DHCPv4 sending/parsing option 209 (PXE config file). Enabled with Kconfig BOOTP_PXE_DHCP_OPTION. Note, this patch was submitted previously but this latest version has been enhanced to avoid a possible double free().

[PATCH v3 0/6] Implement proper sysreset ability for Tegra SoCs and some PMICs
by Svyatoslav Ryhel 03 Oct '23

03 Oct '23

This patchset converts do_reset from mach-tegra function to a proper sysreset dm driver with saving all its previous abilities. Additionally implement do_poweroff (since Tegra sysreset can only reset) by making sysreset drivers for the most widely used PMICs on Tegra devices. This includes sysreset cells for MAX77663, TPS80031/TPS80032, TPS65910/TPS65911 and PALMAS PMIC family. All drivers are tested on actual hardware and confirmed to work as expected. These patches require "Add support for PMICs used on Tegra 3 devices" patches to be merged first for proper work. --- Changes from v2: - no changes, re-sending Changes from v1: - move variable declaration from switch --- Svyatoslav Ryhel (6): sysreset: tegra: create arch specific sysreset driver arm: mach-tegra: enable sysreset driver sysreset: implement MAX77663 sysreset functions sysreset: implement TPS80031 sysreset functions sysreset: implement TPS65910 sysreset functions sysreset: implement PALMAS sysreset functions arch/arm/mach-tegra/Kconfig | 3 ++ arch/arm/mach-tegra/pmc.c | 9 ----- drivers/power/pmic/max77663.c | 12 +++++- drivers/power/pmic/palmas.c | 33 +++++++++++++++- drivers/power/pmic/pmic_tps65910_dm.c | 12 +++++- drivers/power/pmic/tps80031.c | 12 +++++- drivers/sysreset/Kconfig | 36 ++++++++++++++++++ drivers/sysreset/Makefile | 5 +++ drivers/sysreset/sysreset_max77663.c | 53 ++++++++++++++++++++++++++ drivers/sysreset/sysreset_palmas.c | 53 ++++++++++++++++++++++++++ drivers/sysreset/sysreset_tegra.c | 46 ++++++++++++++++++++++ drivers/sysreset/sysreset_tps65910.c | 55 +++++++++++++++++++++++++++ drivers/sysreset/sysreset_tps80031.c | 41 ++++++++++++++++++++ include/power/max77663.h | 5 +++ include/power/palmas.h | 11 ++++++ include/power/tps65910_pmic.h | 7 ++++ include/power/tps80031.h | 5 +++ 17 files changed, 384 insertions(+), 14 deletions(-) create mode 100644 drivers/sysreset/sysreset_max77663.c create mode 100644 drivers/sysreset/sysreset_palmas.c create mode 100644 drivers/sysreset/sysreset_tegra.c create mode 100644 drivers/sysreset/sysreset_tps65910.c create mode 100644 drivers/sysreset/sysreset_tps80031.c -- 2.39.2

[PATCH v7 0/8] Add support for PMICs used on Tegra 3 devices
by Svyatoslav Ryhel 03 Oct '23

03 Oct '23

Patch set adds basic support for PMICs used in many Tegra 3 devices. All PMIC drivers are based on datasheets provided by vendors. Implemented API include regulator set/get voltage enable/disable and basic PMIC r/w capabilities. Drivers were tested by me on LG P895 (max77663), HTC One X (TPS80032) and ASUS TF300T (tps65911). Calculations and behavior were correct, predictable and reproducible. Poweroff functional will be added after this basic drivers are merged. --- Changes from v6: - no changes, re-sending Changes from v5: - pass tps6591x regulator children directly via udevice_id data field Changes from v4: - used private structure for TPS80031 SPMS driver so that internal flags do not interfere with those from dm_regulator_uclass_plat - fixed detection on ldoln and ldousb for palmas ldo driver Changes from v3: - expanded descriptions in Kconfigs for pmics and regulators - replaced ret with other variable name if it is not used for return - dropped prefixed with pmic name - dropped () in ~(var) type expressions - return dm_i2c_* output in pmic_read/write functions - switched to log_debug in some places - added descryptions for some "non obvious" functions - fixed tps80031 spms voltage calculation in non linear region - adjsuted tps65911 vio voltage calculation Changes from v2: - removed all previously made poweroff API in favour to use sysreset after this patchset is accepted Changes from v1: - created poweroff API for PMIC and integrated it call into do_poweroff - added poweroff function to submitted max77663, tps80032 and tps65911 drivers - fixed registers asignments for regulators with non-numeric name (ldoln, ldousb, vddctrl) --- Svyatoslav Ryhel (8): power: pmic: palmas: support TI TPS65913 PMIC power: regulator: palmas: fix ldoln and ldousb detection power: pmic: add the base MAX77663 PMIC support power: regulator: max77663: add regulator support power: pmic: add the base TPS80031 PMIC support power: regulator: tps80031: add regulator support power: pmic: tps65910: add TPS65911 PMIC support power: regulator: tps65911: add regulator support doc/device-tree-bindings/pmic/max77663.txt | 84 ++++ doc/device-tree-bindings/pmic/tps65911.txt | 78 ++++ doc/device-tree-bindings/pmic/tps80031.txt | 76 ++++ drivers/power/pmic/Kconfig | 20 + drivers/power/pmic/Makefile | 2 + drivers/power/pmic/max77663.c | 86 ++++ drivers/power/pmic/palmas.c | 1 + drivers/power/pmic/pmic_tps65910_dm.c | 15 +- drivers/power/pmic/tps80031.c | 87 ++++ drivers/power/regulator/Kconfig | 28 ++ drivers/power/regulator/Makefile | 3 + drivers/power/regulator/max77663_regulator.c | 378 ++++++++++++++++++ drivers/power/regulator/palmas_regulator.c | 24 +- drivers/power/regulator/tps65911_regulator.c | 397 +++++++++++++++++++ drivers/power/regulator/tps80031_regulator.c | 350 ++++++++++++++++ include/power/max77663.h | 42 ++ include/power/tps65910_pmic.h | 44 ++ include/power/tps80031.h | 45 +++ 18 files changed, 1747 insertions(+), 13 deletions(-) create mode 100644 doc/device-tree-bindings/pmic/max77663.txt create mode 100644 doc/device-tree-bindings/pmic/tps65911.txt create mode 100644 doc/device-tree-bindings/pmic/tps80031.txt create mode 100644 drivers/power/pmic/max77663.c create mode 100644 drivers/power/pmic/tps80031.c create mode 100644 drivers/power/regulator/max77663_regulator.c create mode 100644 drivers/power/regulator/tps65911_regulator.c create mode 100644 drivers/power/regulator/tps80031_regulator.c create mode 100644 include/power/max77663.h create mode 100644 include/power/tps80031.h -- 2.39.2

[PATCH v3 0/3] Video: Keep fixed/gpio regulator counter in balance
by Svyatoslav Ryhel 03 Oct '23

03 Oct '23

The commit 4fcba5d556b4 ("regulator: implement basic reference counter") have made it more important to keep fixed/gpio regulators enable/disable state in balance. The regulator_set_enable_if_allowed function is more relaxed and will wrap all cases where the regulator is busy, already active, missing or if DM_REGULATOR is not enabled. These patches are an expansion of similar Jonas Karlman's patches. --- Changes from v2: - no changes, re-sending Changes from v1: - check return of regulator_set_enable_if_allowed for -ENOSYS to avoid error caused by disabled DM_REGULATOR (Jonas Karlman suggestion) --- Svyatoslav Ryhel (3): video: pwm_backlight: use regulator_set_enable_if_allowed video: simple_panel: use regulator_set_enable_if_allowed video: tegra20: dsi: use regulator_set_enable_if_allowed drivers/video/pwm_backlight.c | 13 ++++++------- drivers/video/simple_panel.c | 10 +++++----- drivers/video/tegra20/tegra-dsi.c | 8 +++----- 3 files changed, 14 insertions(+), 17 deletions(-) -- 2.39.2

[PATCH v2 1/1] input: avoid NULL dereference
by Heinrich Schuchardt 03 Oct '23

03 Oct '23

Before using the result of env_get("stdin") we must check if it is NULL. Avoid #if. This resolves the -Wunused-but-set-variable issue and we don't need a dummy assignment in the else branch.
