2023-04-30Merge branch 'master' of https://source.denx.de/u-boot/custodians/u-boot-sunxiTom Rini
Please pull the second part of the sunxi pull request for this cycle. Another bunch of patches that replace old-school U-Boot hacks with proper DM based code, this time for the raw NAND flash driver, and the USB PHY VBUS detection code. Plus two smaller patches that were sitting in my inbox for a while. Gitlab CI passed. In lack of some supported board with NAND flash I couldn't really test this part, but apparently this was tested by the reviewer. I briefly ran the branch on some boards with USB-OTG, and this still worked.

https://source.denx.de/u-boot/custodians/u-boot-mpc8xx This pull request adds support for the last CPU board from CS GROUP France (previously CSSI). That CPU board called CMPCPRO has a mpc8321E CPU (Family PQII PRO hence its name) and can be plugged in place of the CMPC885 board. In order to support that new board, the following changes are included in this series: - Make the mpc8xx watchdog driver more generic for reusing it with mpc83xx - Fix various small problems on mpc83xx platform - Add a GPIO Driver for QE GPIOs - Add support for mpc832x into mpc83xx SPI driver - Refactor existing board code that will be shared with new board - Add the new board
2023-04-28clk: sunxi: Add NAND clocks and resetsSamuel Holland
Currently NAND clock setup is done in board code, both in SPL and in U-Boot proper. Add the NAND clocks/resets here so they can be used by the "full" NAND driver once it is converted to the driver model. The bit locations are copied from the Linux CCU drivers.

2023-04-21rockchip: rk3588: Add support for sdmmc clocks in SPLJonas Karlman
Booting from sdmmc on RK3588 currently works because of a workaround in the device tree, clocks are reordered so that the driver use ciu-sample instead of ciu, and the BootRom initializes sdmmc clocks before SPL is loaded into DRAM. The sdmmc clocks are normally controlled by TF-A using SCMI. However, there is a need to control these clocks in SPL, before TF-A has started. This adds a rk3588_scru driver to control the sdmmc clocks in SPL before TF-A has started, using scru regs. It also adds a small glue driver to bind the scmi clock node to the rk3588_scru driver in SPL.

2023-04-07clk: renesas: Update R-Car Gen3 driver Gen4 supportMarek Vasut
Update R-Car Gen4 support in Gen3 clock driver. This patch renames the V3U clock parts to Gen4 and extends them by new PLL2, PLL3, PLL4, PLL6 as well as SDSRC clock which use undocumented bits so far, and RPCSRC clock which uses its own more capable divider table. The Gen4 module standby and reset tables are also updated. This patch makes use of union to alias Gen3 and more extensive Gen4 PLL tables, as the driver cannot ever be instantiated on hardware that would identify itself as both Gen3 and Gen4. The V3U clock driver is updated to match Gen4 clock driver behavior, it is augmented with a more extensive PLL table and a valid MODEMR register offset. This supersedes "clk: renesas: Introduce R-Car Gen4 CPG driver" from Hai Pham as the R-Car Gen3 and Gen4 clock core drivers are extremely similar. That implementation was in turn based on Linux commit 470e3f0d0b15 ("clk: renesas: rcar-gen4: Introduce R-Car Gen4 CPG driver") by Yoshihiro Shimoda .

Ensure the reset framework is also always enabled to prevent inobvious early boot time bind failure of the CPG driver, which leads to system showing no activity and is difficult to debug.

R-Car V3U has a CPG different enough to not be a generic Gen3 CPG but similar enough to reuse code. Introduce a new CPG library, factor out the SD clock and RPC clock handling and hook them to the generic Gen3 CPG driver so we have an equal state.

2023-02-02clk: renesas: Add R8A77970 SD0H/SD0 clocks for SDHIHai Pham
On R-Car V3M (AKA R8A77970), the SD0CKCR is laid out differently than on the other R-Car gen3 SoCs. Hence, new clock types are introduced respectively. Based on Linux commit 381081ffc294 ("clk: renesas: r8a77970: Add SD0H/SD0 clocks for SDHI") by Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> Signed-off-by: Hai Pham <hai.pham.ud@renesas.com> Signed-off-by: Marek Vasut <marek.vasut+renesas@mailbox.org> Marek: - Fix missing ~ in GENMASK(a, b), use clrsetbits_le32 instead - Do not modify r8a77970-cpg-mssr.c much, drop enum r8a77970_clk_types which is now part of common clock types in rcar-gen3-cpg.h instead
2023-02-02clk: renesas: Switch to new SD clock handlingHai Pham
The old SD handling code was huge and could not handle all the details which showed up on R-Car Gen3 SoCs meanwhile. It is time to switch to another design. Have SDnH a separate clock, use the existing divider clocks and move the errata handling from the clock driver to the SDHI driver where it belongs. Based on Linux series by Wolfram Sang, commit bb6d3fa98a41 ("clk: renesas: rcar-gen3: Switch to new SD clock handling") and commit e5f7e81ee430a ("mmc: renesas_sdhi: Parse DT for SDnH") Signed-off-by: Hai Pham <hai.pham.ud@renesas.com> Signed-off-by: Marek Vasut <marek.vasut+renesas@mailbox.org> Marek: - Add rcar_clk_* prefix to all functions - Fix missing ~ in GENMASK(a, b), use clrsetbits_le32 instead - Use DIV_ROUND_CLOSEST, else if parent clock = 199999992 and rate = 200000000, the divider would be 0 and table lookup would fail. - Turn rcar_clk_get_table_val into signed integer, so it can return 0 as a valid value and negative values as errors. - Make the code operate on correct clock and add comment which explains the reasoning behind it. - Rebase on changes to clk: renesas: Introduce and use rcar_clk_get_rate64_div_table function
2023-02-02clk: renesas: Handle E3/D3 RPCSRC clockHai Pham
The RPCSRC clock divider on R-Car D3 is very similar to the one on R-Car E3, but uses a different pre-divider for the PLL0 parent. Add a new macro to describe it, reusing the existing clock type for R-Car E3. As both E3/D3 RPCSRC clock divider are different from the rest of R-Car Gen3, keep the original implementation from Linux. Based on Linux commit 40745482eec8 ("clk: renesas: r8a774c0: Add RPC clocks") by Lad Prabhakar and 9d18f81b3535 ("clk: renesas: r8a77995: Add RPC clocks") by Geert Uytterhoeven.

2023-02-02clk: renesas: Introduce and use rcar_clk_get_rate64_div_table functionHai Pham
Introduce new helper function to handle clock type that uses clk_div_table struct. Based vaguely on Linux code. Make use of clk_div_table in RPC clocks handling. The E3/D3 RPCSRC need to be handled differently and will be addressed in subsequence patch. Based on Linux commit db4a0073cc82 ("clk: renesas: rcar-gen3: Add RPC clocks") by Sergei Shtylyov.

Use custom field_get implementation as the generic FIELD_GET does not support constant mask and u32_get_bits requires higher optimization level - Pass in the register bit mask instead of width/shift combination - Turn rcar_clk_get_rate64_div_table into s64, as it can return -EINVAL
