This pull request adds misc fixes for cssi boards and activates CPM relocation in order to enable the use of SCC4 in QMC (QUICC Multi-Channel) mode.

serial, mpc8xx: Take parameter RAM relocation into account

2023-05-05T05:26:53Z

Instead of inhibiting parameter RAM relacation, take into account the configured one. It means INIT_TRX command cannot be used and must be done manually as explained in the microcode patch application note. Signed-off-by: Christophe Leroy

powerpc: mpc8xx: CPM parameter RAM can be anywhere

2023-05-04T08:58:07Z

With relocation, CPM parameter RAM can be anywhere in the dual port RAM, so don't split dual port RAM. Remove dparam and dparam16 members of struct comm_proc PROFF_XXX become offsets from the start of dual port RAM, then they are now consistant with the offsets in RPBASE registers.

serial: msm-geni: correct oversampling value based on QUP hardware revision

2023-05-02T18:23:59Z

Starting from QUP v2.5 the value of oversampling is changed from 32 to 16, keeping the old value on newer platforms results on wrong set UART IP clock divider, thus the asked baudrate does not correspond to the actually set with all the consequencies for a user. The change links the driver to a new Qualcomm GENI SE QUP driver to get its hardware version and update the oversampling value. Deliberately the code under CONFIG_DEBUG_UART_MSM_GENI is not touched, since a wanted baudrate can be controlled by setting a modified CONFIG_DEBUG_UART_CLOCK build time variable.

serial: msm-geni: Use upstream Linux bindings

2023-05-02T18:23:58Z

The name "se" is used in upstream Linux device trees and has been for ages, long before this U-Boot-ism was introduced. Same goes for the existing compatible. Get rid of that. [vzapolskiy: removed a ready change in the driver] Signed-off-by: Konrad Dybcio Signed-off-by: Vladimir Zapolskiy

serial: msm-geni: fix a compile time warning from msm_serial_setbrg()

2023-05-02T18:23:58Z

A compiler warns about a missing function prototype, which is valid and fixed by converting the function into static one, also fix interleaved local variable declarations and assignments.

serial: msm-geni: fix code indentation

2023-05-02T18:23:58Z

This a cosmetic change, which corrects code indentation in a few places. Signed-off-by: Vladimir Zapolskiy Reviewed-by: Konrad Dybcio

serial: msm-geni: remove invalid se-clk clock name

2023-05-02T18:23:58Z

There is only one clock supplier to the serial IP, thus getting it by name is not needed, also note that "clock-names" property is not listed under doc/device-tree-bindings/serial/msm-geni-serial.txt, and finally "se-clk" clock name is invalid, if added, it shall get "se" value like it's already described in Linux device tree documentation.

serial: msm-geni: Always bind before relocation

In preparation for supporting upstream Linux device trees on Qualcomm platforms, make this the default behavior. [vzapolskiy: extracted the driver change from a combination with dts changes] Signed-off-by: Konrad Dybcio Signed-off-by: Vladimir Zapolskiy

serial: msm-geni: remove redundant includes

2023-05-02T18:23:58Z

For whatever reason, likely a driver stub was copied from another driver, the driver contains a bunch of unnecessary and confusing includes like watchdog.h etc., the change reduces the list. Signed-off-by: Vladimir Zapolskiy Reviewed-by: Konrad Dybcio
