pinctrl: rockchip: Fix drive and input schmitt on RK3568

2023-08-14T03:07:27Z

On RK3568 most pins have a configurable drive strength of level 0-5 and some pins level 0-11. When rk3568_set_drive is called with a strength value above 7 the drv value written to reg may overflow into the write enable bits, resulting in a bad configuration. This cause e.g. ethernet PHY on Radxa CM3-IO board not to work after drive is configured according to the device tree. Could not get PHY for ethernet@fe010000: addr 0 Level 6-11 can be configured using a second reg for some pins, however the drv value is reused resulting in lower 6 bits being written to reg. Input schmitt is configured in 2-bit fields on RK3568 compared to earlier generation and 2'b10 should be used to enable input schmitt. Change to use regmap_update_bits with a rmask to fix the overflow issue and closer match the linux driver. Bit shift the drv value used for the second reg to configure drive strength level 6-11. Also write correct values for input schmitt setting. Fixes: 1977d746aa54 ("rockchip: rk3568: add rk3568 pinctrl driver") Signed-off-by: Jonas Karlman Reviewed-by: Simon Glass Reviewed-by: Kever Yang

pinctrl: rockchip: Fix Data Abort exception in SPL

2023-06-29T10:42:58Z

Using CONFIG_ARMV8_SPL_EXCEPTION_VECTORS=y and CONFIG_OF_LIVE=y triggers a Data Abort exception from unaligned memory access when the pinctrl driver iterate node properties, e.g. for UART2 on RK3568. setting mux of GPIO0-24 to 1 setting mux of GPIO0-24 to 1 "Synchronous Abort" handler, esr 0x96000021 elr: 000000000000e554 lr : 000000000000e54c x 0: 0000000000000a5c x 1: 0000000000000a5c x 2: 0000000000000007 x 3: 0000000000000065 x 4: 0000000000000007 x 5: 0000000000022d4e x 6: 0000000000000a7c x 7: 00000000000227a4 x 8: 0000000000021cf0 x 9: 0000000000000a7c x10: 0000000000021cf0 x11: 0000000000021cf0 x12: 00000000003fda1c x13: 0000000000000007 x14: 00000000003fd9ec x15: 000000000001c0ff x16: 0000000007000000 x17: 00000000fdccd028 x18: 00000000003fde20 x19: 0000000000000018 x20: 0000000000020670 x21: 0000000000000000 x22: 00000000003fdb00 x23: 00000000003fef90 x24: 0000000000020688 x25: 0000000000000000 x26: 0000000000000001 x27: 00000000003ffc50 x28: 0000000000000000 x29: 00000000003fda60 Code: b94083e1 97ffd508 93407c01 37f81260 (f9401038) Resetting CPU ... Fix this by replacing the loop to access node properties with use of ofnode_for_each_prop instead of the current ifdef. Also continue to next prop instead of aborting at first sign of an unknown property.

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42Z

Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include at all, so remove that include. Signed-off-by: Simon Glass Signed-off-by: Tom Rini
