* mmc: dwmmc: Change designware MMC 'clksel' callback function to return statusSiew Chin Lim2021-01-155-6/+19
| | | | | | | | | | | | | | | | | Change 'clksel' callback function to allow the code to return a status. This patch is a preparation for enabling Arm-Trusted-Firmware (ATF) in Intel SoC FPGA. This patch does not change functionality. When using Arm-Trusted-Firmware (ATF) in Intel SoC FPGA, the MMC clock related register is secure register which is required to be written via SMC/PCSI call. It is possible that U-Boot fail to write the register if there is unexpected error between U-Boot and ATF. As a result, there maybe signal integrity on MMC connection due to clock. So, the code should reports error to user when 'clksel' fail. Signed-off-by: Siew Chin Lim <elly.siew.chin.lim@intel.com>

* | remoteproc: ti_k3_arm64: Program CNTFID0 register in GTCNishanth Menon2021-01-121-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ARMv8's generic timer[1] picks up it's graycode from GTC. However, the frequency of the GTC is supposed to be programmed in CNTFID0[2] register prior to enabling the GTC in CNTCR[3] register. In K3 architecture, GTC provides a central time to many parts of the SoC including graycode to the generic timer in the ARMv8 subsystem. However, due to the central nature and the need to enable the counter early in the boot process, the R5 based u-boot enables GTC and programs it's frequency based on central needs of the system. This may not be a constant 200MHz based on the system. The bootloader is supposed to program the FID0 register with the correct frequency it has sourced for GTC from the central system controller OR from PLLs as appropriate, and TF-A is supposed[4] to use that as the frequency for it's local timer. Currently we are programming just the CNTCR[3] register to enable the GTC, however we dont let TF-A know the frequency that GTC is actually running at. A mismatch in programmed frequency and what we program for generic timer will, as we can imagine, all kind of weird mayhem. So, program the CNTFID0 register with the clock frequency. Note: assigned-clock-rates should have set the clock frequency, so the only operation we need to explicitly do is to retrieve the frequency and program it in FID0 register. Since the valid in K3 for GTC clock frequencies are < U32_MAX, we can just cast the ulong and continue.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The schedule for deprecating the features of the pre-driver-model puts 2019.17 as the deadline for the video subsystem. Furthermore, the latest patches applied to the am335x-fb.c module have decreased the amount of code shared with the pre-driver-model implementation. Splitting the two implementations into two modules improves the readability of the code and will make it easier to drop the pre-driver-model code. I have not created a header file with the data structures and the constants for accessing the LCD controller registers, but I preferred to keep them inside the two c modules. This is a code replication until the pre-driver-model version is dropped. Signed-off-by: Dario Binacchi <dariobin@libero.it>
