[PATCH 00/23] Add i.MX8ULP A1 revision support
by Ye Li 29 Mar '23

29 Mar '23

The patch set is used to support i.MX8ULP A1 revision. It includes below changes: a) XRDC/TRDC are enabled by default on A1 via DBD_EN fuse programmed. So necessary changes for XRDC setting are added. And TRDC is totally moved to RTD. A handshake is added to sync with RTD for the XRDC and TRDC setting completion. b) S400 API update and fuse update c) DDR timing and driver update d) clock setting update to match max rate restriction e) uPower API update and code clean Jacky Bai (2): ddr: imx: Update the ddr init flow on imx8ulp imx8ulp_evk: Update the DDR timing Peng Fan (3): imx: imx8ulp: upower: replace magic number with macro imx: imx8ulp: upower: make code cleaner imx8ulp_evk: disable overflow of port0 for LPAV Ye Li (18): imx: imx8ulp: Fix MU device probe failure imx: imx8ulp: Get chip revision from Sentinel imx: imx8ulp: Limit the eMMC ROM API workaround to A0.1 part imx: imx8ulp: Set XRDC MRC4/5 for access DDR from APD imx: imx8ulp: Remove the TRDC configure from A35 imx: imx8ulp: Adjust handshake to sync TRDC and XRDC completion imx: imx8ulp: configure XRDC for DRAM access from S400 ddr: imx8ulp: Change DRAM timing save area to 0x20055000 imx: imx8ulp: Reconfigure MRC3 for SRAM0 access imx: imx8ulp: Clear dividers in PLL3DIV_PFD registers imx: imx8ulp: Configure XRDC PDAC and MSC for DBD owner=S400 only imx: imx8ulp: Update clocks to meet max rate restrictions imx: sentinel: Update S400 API get info message structure misc: fuse: Update fuse mapping for 8ULP S400 API misc: fuse: Lock 8ULP ECC-protected fuse when programming imx8ulp_evk: Change to use DDR driver imx8ulp_evk: Update DDR ports arbitration for DCNANO underrun imx8ulp_evk: Clear data at fdt_addr_r before booting kernel arch/arm/include/asm/arch-imx8ulp/imx-regs.h | 1 + arch/arm/include/asm/arch-imx8ulp/rdc.h | 1 + arch/arm/include/asm/arch-imx8ulp/sys_proto.h | 2 + arch/arm/include/asm/global_data.h | 3 + arch/arm/include/asm/mach-imx/s400_api.h | 2 + arch/arm/mach-imx/imx8ulp/Kconfig | 1 + arch/arm/mach-imx/imx8ulp/cgc.c | 70 ++++---- arch/arm/mach-imx/imx8ulp/clock.c | 50 +++--- arch/arm/mach-imx/imx8ulp/rdc.c | 71 ++++++++ arch/arm/mach-imx/imx8ulp/soc.c | 208 ++++++++++++++++++----- arch/arm/mach-imx/imx8ulp/upower/upower_hal.c | 112 +++++++++++-- board/freescale/imx8ulp_evk/Makefile | 2 +- board/freescale/imx8ulp_evk/ddr_init.c | 207 ----------------------- board/freescale/imx8ulp_evk/imx8ulp_evk.c | 16 +- board/freescale/imx8ulp_evk/lpddr4_timing.c | 210 ++++++++++++------------ board/freescale/imx8ulp_evk/lpddr4_timing_266.c | 6 +- board/freescale/imx8ulp_evk/spl.c | 18 +- drivers/ddr/imx/imx8ulp/Kconfig | 2 +- drivers/ddr/imx/imx8ulp/ddr_init.c | 55 +++++-- drivers/misc/sentinel/fuse.c | 32 +++- 20 files changed, 605 insertions(+), 464 deletions(-) delete mode 100644 board/freescale/imx8ulp_evk/ddr_init.c -- 2.7.4

[PATCH] renesas: rcar: Apply ATF overlay for reserved-memory
by Detlev Casanova 23 Mar '23

23 Mar '23

The function fdtdec_board_setup() is only called by fdtdec_setup() which needs to be called by the board file. This is not the case for the renesas boards so rename the fdtdec_board_setup() function to a local name and call it directly from ft_board_setup(), before cleaning up the memory nodes.

[PATCH] i2c: correct I2C deblock logic
by haibo.chen＠nxp.com 23 Mar '23

23 Mar '23

From: Haibo Chen <haibo.chen(a)nxp.com> Current code use dm_gpio_get_value() to get SDA and SCL value, and the value depends on the flag GPIOD_ACTIVE_LOW. When toggle SCL to wait slave release SDA, the SDA are config as GPIOD_IS_IN, and whether contain the GPIOD_ACTIVE_LOW depends on the DTS setting. Usually, for I2C GPIO, we use GPIOD_ACTIVE_LOW flag in DTS, so if the SDA is in low level, then dm_gpio_get_value() will return 1, current code logic will stop the SCL toggle wrongly, cause the I2C deblock not work as expect. This patch force set the GPIOD_ACTIVE_LOW for both GPIOD_IS_IN and GPIOD_IS_OUT, and make the return value of i2c_gpio_get_pin() eaqual to the physical voltage logic level.
