[PATCH 1/3] firmware: scmi: voltage regulator
by Etienne Carriere 19 Feb '21

19 Feb '21

Implement voltage regulators interfaced by the SCMI voltage domain protocol. The DT bindings are defined in the Linux kernel since SCMI voltage domain and regulators patches [1] and [2] integration in v5.11-rc7.

[PATCH] fdt/sunxi: Remove OF_STDOUT_PATH
by Andre Przywara 19 Feb '21

19 Feb '21

OF_STDOUT_PATH was meant to hold the devicetree path to the serial console, to be put into the linux,stdout-path property of the chosen node. The only user of that was sunxi, and it was actually wrong for years there: the paths hardcoded in sunxi_common.h were not matching the DTs, evident by the leading 0's in nodenames, which have been removed years ago. On top of that, "linux,stdout-path" is now deprecated for a while (Linux commit 2a9d832cc9aae from November 2014), and also all modern DTs (including those included in U-Boot) carry a "stdout-path" property already. So remove the stanza from sunxi_common.h, and, since this was the last user, also remove the associated bits from the rest of U-Boot.

[GIT PULL] rpi: updates for v2021.04
by Matthias Brugger 18 Feb '21

18 Feb '21

Hi Tom, Please find below the updates for the Raspberry Pi for v202.04. The most important are the support for Compute Module 4 and RPi400. Apart from that we now have support for the RNG device found on RPi4. I run the patches through the gitlab CI: https://gitlab.denx.de/u-boot/custodians/u-boot-raspberrypi/-/pipelines/6416 https://gitlab.denx.de/u-boot/custodians/u-boot-raspberrypi/-/pipelines/6415 It took quite a while to get all this patches ready for mainline, as the pytests were failing. This is got fixed by Andy Shevchenko and is now merge upstream, so everything is green :) Regards, Matthias --- The following changes since commit 496f49464d90b564da5f1a2f4eecb5553e01edf9: Merge branch '2021-02-16-assorted-improvements' (2021-02-16 15:14:34 -0500) are available in the Git repository at: https://gitlab.denx.de/u-boot/custodians/u-boot-raspberrypi.git tags/rpi-next-2021.04 for you to fetch changes up to 0059ef0be903a1f0a9afe5259fb2e0874f78a8ac: video: arm: rpi: Add brcm,bcm2711-hdmi0 compatible (2021-02-18 11:59:08 +0100) ---------------------------------------------------------------- - add iProc RNG2000 driver for RPi4 - add support for CM4 and RPi400 ---------------------------------------------------------------- Marek Szyprowski (1): rpi: limit size of the RAM to the multiple of the MMU_SECTION_SIZE Matthias Brugger (2): rng: Add iProc RNG200 driver config: Enable iProc RNG200 driver in RPi4 configs Nicolas Saenz Julienne (15): usb: xhci-pci: Add DM_FLAG_OS_PREPARE flag pci: brcmstb: Cleanup controller state before handover rpi: Add identifier for the new RPi400 rpi: Add identifier for the new CM4 pci: pcie-brcmstb: Fix inbound window configurations dm: Introduce xxx_get_dma_range() dm: test: Add test case for dev_get_dma_ranges() dm: Introduce DMA constraints into the core device model dm: test: Add test case for dev->dma_offset dm: Introduce dev_phys_to_bus()/dev_bus_to_phys() dm: test: Add test case for dev_phys_to_bus()/dev_bus_to_phys() xhci: translate virtual addresses into the bus's address space mmc: Introduce mmc_phys_to_bus()/mmc_bus_to_phys() configs: rpi4: Enable DM_DMA across all RPi4 configurations video: arm: rpi: Add brcm,bcm2711-hdmi0 compatible arch/sandbox/dts/test.dts | 21 +++++ board/raspberrypi/rpi/rpi.c | 17 ++++ common/fdt_support.c | 73 +++++++++++++++ configs/rpi_4_32b_defconfig | 1 + configs/rpi_4_defconfig | 3 + configs/rpi_arm64_defconfig | 3 + configs/sandbox64_defconfig | 1 + configs/sandbox_defconfig | 1 + configs/sandbox_flattree_defconfig | 1 + configs/sandbox_spl_defconfig | 1 + drivers/core/Kconfig | 10 ++ drivers/core/device.c | 41 ++++++++ drivers/core/of_addr.c | 78 ++++++++++++++++ drivers/core/ofnode.c | 9 ++ drivers/core/read.c | 6 ++ drivers/mmc/sdhci.c | 10 +- drivers/pci/pcie_brcmstb.c | 32 +++++-- drivers/rng/Kconfig | 6 ++ drivers/rng/Makefile | 1 + drivers/rng/iproc_rng200.c | 185 +++++++++++++++++++++++++++++++++++++ drivers/usb/host/xhci-mem.c | 45 ++++----- drivers/usb/host/xhci-pci.c | 2 +- drivers/usb/host/xhci-ring.c | 13 ++- drivers/usb/host/xhci.c | 4 +- drivers/video/bcm2835.c | 1 + include/dm/device.h | 13 +++ include/dm/of_addr.h | 17 ++++ include/dm/ofnode.h | 16 ++++ include/dm/read.h | 21 +++++ include/fdt_support.h | 14 +++ include/mmc.h | 6 ++ include/phys2bus.h | 17 ++++ include/usb/xhci.h | 20 +++- test/dm/Makefile | 2 + test/dm/core.c | 30 ++++++ test/dm/phys2bus.c | 37 ++++++++ test/dm/read.c | 49 ++++++++++ 37 files changed, 766 insertions(+), 41 deletions(-) create mode 100644 drivers/rng/iproc_rng200.c create mode 100644 test/dm/phys2bus.c create mode 100644 test/dm/read.c

[PATCH v7 0/5] VIM3: add support for checking 'Function' button state
by Marek Szyprowski 18 Feb '21

18 Feb '21

Hi All, This patchset adds all building blocks needed for checking the 'Function' button state in the boot script on Amlogic A311D based VIM3 board. This button is connected to the ADC line of the SoC, so it required to enable meson SARADC, the clocks needed for it and a simple button-adc drivers. Once applied, one can use following commands in the boot scripts: -->8--- echo Checking Func button state: \\c if button Function then echo Selected alternative boot ... fi --->8--- Best regards Marek Szyprowski Samsung R&D Institute Poland Changelog: v7: - added linux,code properties to the test.dts v6: https://lists.denx.de/pipermail/u-boot/2021-February/441039.html - added a simple sandbox test for adc-keys - use of_to_plat and adc_raw_to_uV to simplify code in the adc button driver v5: https://lists.denx.de/pipermail/u-boot/2021-January/438751.html - rebased onto latest uboot-amlogic/u-boot-amlogic-next branch - synchronized adc-keys binding with the recent version from the Linux kernel - updated adc-keys driver to match behavior from dt-bindings - added a patch for meson-saradc driver to register vdd reference supply to the ADC framework v4: https://lists.denx.de/pipermail/u-boot/2020-December/435641.html - rebased onto uboot-amlogic/u-boot-amlogic-next and dropped merged patches - added adc-keys bindings docs (copied from Linux kernel) - minor code adjustments pointed by Simon - enabled driver also in khadas-vim3l_defconfig v3: https://lists.denx.de/pipermail/u-boot/2020-December/435072.html - removed 'button' env variable - extended kconfig and patch descriptions v2: https://lists.denx.de/pipermail/u-boot/2020-December/434991.html - removed Change-Id tags - split defconfig changes into ADC and button related v1: https://lists.denx.de/pipermail/u-boot/2020-December/434875.html - initial submission Patch summary: Marek Szyprowski (5): dt-bindings: input: adc-keys bindings documentation button: add a simple Analog to Digital Converter device based button driver adc: meson-saradc: add support for getting reference voltage value configs: khadas-vim3(l): enable Function button support test: add a simple test for the adc-keys button driver arch/sandbox/dts/test.dts | 27 +++- configs/khadas-vim3_defconfig | 2 + configs/khadas-vim3l_defconfig | 2 + configs/sandbox_defconfig | 1 + doc/device-tree-bindings/input/adc-keys.txt | 67 +++++++++ drivers/adc/meson-saradc.c | 21 +++ drivers/button/Kconfig | 8 ++ drivers/button/Makefile | 1 + drivers/button/button-adc.c | 146 ++++++++++++++++++++ test/dm/button.c | 50 ++++++- 10 files changed, 322 insertions(+), 3 deletions(-) create mode 100644 doc/device-tree-bindings/input/adc-keys.txt create mode 100644 drivers/button/button-adc.c -- 2.17.1
