serial: msm-geni: handle devm_clk_get() errors

2024-01-16T12:26:53Z

devm_clk_get() returns an ERR_PTR on failure, not null. Fix the check to avoid the board crashing when the clock isn't available. Additionally, add the missing error handling for this function. Fixes: 324df15a292e ("serial: qcom: add support for GENI serial driver") Signed-off-by: Caleb Connolly

serial: msm-geni: don't rely on parent misc device

2024-01-16T12:26:52Z

commit 1b15483deb3f ("misc: add Qualcomm GENI SE QUP device driver") introduced support for platform-specific oversampling values, necessary to configure the UART clocks on all platforms at runtime. However it relies in probing a parent device. Despite the DM_FLAG_PRE_RELOC flag, this is not done consistently during boot. Instead, take another approach by relying on ofnode_ helpers to read the serial engine base address and do the read directly. This fixes early UART on boards with a non-default oversampling rate.

serial: s5p: Use dev_read_addr_ptr() to get base address

2023-11-27T09:04:11Z

As the address read from device tree is being cast to a pointer, it's better to use dev_read_addr_ptr() API for getting that address. The more detailed explanation can be found in commit a12a73b66476 ("drivers: use dev_read_addr_ptr when cast to pointer").

serial: s5p: Use livetree API to get "id" property

2023-11-23T06:24:18Z

Use dev_read_u8_default() instead of fdtdec_get_int() to read the "id" property from device tree, as suggested in [1]. dev_* API is already used in this driver, so there is no reason to stick to fdtdec_* API. This also fixes checkpatch warning: WARNING: Use the livetree API (dev_read_...)
