| | | * | | clk: rockchip: add sclk_mac_lbtest to rk3188_critical_clocksAlex Bee2020-07-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the loopbacktest clock is not exported and is not touched in the driver, it has to be added to rk3188_critical_clocks to be protected from being disabled and in order to get the emac working.

| | | * | | clk: rockchip: Revert "fix wrong mmc sample phase shift for rk3328"Robin Murphy2020-07-081-4/+4

According to a subsequent revert in the vendor kernel, the original change was based on unclear documentation and was in fact incorrect. Emprically, my board's HS200 eMMC at 200MHZ apparently gets lucky with a phase where this had no impact, but limiting max-frequency to 150MHz to match the nominal capability of the I/O pins made it virtually unusable, constantly throwing errors and retuning. With this revert, it starts behaving perfectly at 150MHz too.

The binding change actually describes the compatibles as one or the other so adapt the code accordingly and add a real second entry-point for the clock controller.

This patch handles this difference by detecting which device-tree we are using. If it is a "rockchip,rk3288-cru", let's register the clock tree as it was before. If the device-tree node is "rockchip,rk3288w-cru", we will apply the difference with this version of this SoC. Noticed that this new device-tree compatible must be handled in bootloader such as u-boot.

Bypass it by zeroing fb_prediv_mask when running on bcm2711. Note that, since the prediv configuration bits were re-purposed, this was triggering miscalculations on all clocks hanging from the VPU clock, notably the aux UART, making its output unintelligible.

Unfortunately, there is no memory check to determine if this allocation fails, it may cause an error when trying to get child node name. This patch will check if the memory allocation fails, and returns and -ENOMEM error instead of blindly moving on.

In the core framework we just have some minor tweaks and a debugfs feature, so not much to see there. The driver updates are fairly well split between AT91 and Qualcomm clk support. Adding those two drivers together equals about 50% of the diffstat. Otherwise, the big amount of work this time was on supporting Broadcom's Raspberry Pi firmware clks. Highlights: Core: - Document clk_hw_round_rate() so it gets some more use - Remove unused __clk_get_flags() - Add a prepare/enable debugfs feature similar to rate setting New Drivers: - Add support for SAMA7G5 SoC clks - Enable CPU clks on Qualcomm IPQ6018 SoCs - Enable CPU clks on Qualcomm MSM8996 SoCs - GPU clk support for Qualcomm SM8150 and SM8250 SoCs - Audio clks on Qualcomm SC7180 SoCs - Microchip Sparx5 DPLL clk - Add support for the new Renesas RZ/G2H (R8A774E1) SoC Updates: - Make defines for bcm63xx-gate clks to use in DT - Support BCM2711 SoC firmware clks - Add HDMI clks for BCM2711 SoCs - Add RTC related clks on Ingenic SoCs - Support USB PHY clks on Ingenic SoCs - Support gate clks on BCM6318 SoCs - RMU and DMAC/GPIO clock support for Actions Semi S500 SoCs - Use poll_timeout functions in Rockchip clk driver - Support Rockchip rk3288w SoC variant - Mark mac_lbtest critical on Rockchip rk3188 - Add CAAM clock support for i.MX vf610 driver - Add MU root clock support for i.MX imx8mp driver - Amlogic g12: add neural network accelerator clock sources - Amlogic meson8: remove critical flag for main PLL divider - Amlogic meson8: add video decoder clock gates - Convert one more Renesas DT binding to json-schema - Enhance critical clock handling on Renesas platforms to only consider clocks that were enabled at boot time" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (79 commits) clk: qcom: gcc: Make disp gpll0 branch aon for sc7180/sdm845 ipq806x: gcc: add support for child probe clk: qcom: msm8996: Make symbol 'cpu_msm8996_clks' static clk: qcom: ipq8074: Add correct index for PCIe clocks clk: <linux/clk-provider.h>: drop a duplicated word clk: renesas: cpg-mssr: Add r8a774e1 support dt-bindings: clock: renesas,cpg-mssr: Document r8a774e1 clk: Drop duplicate selection in Kconfig clk: qcom: smd: Add support for MSM8992/4 rpm clocks clk: qcom: ipq8074: Add missing clocks for pcie dt-bindings: clock: qcom: ipq8074: Add missing bindings for PCIe Replace HTTP links with HTTPS ones: Common CLK framework clk: qcom: Add CPU clock driver for msm8996 dt-bindings: clk: qcom: Add bindings for CPU clock for msm8996 soc: qcom: Separate kryo l2 accessors from PMU driver clk: meson: meson8b: add the vclk2_en gate clock clk: meson: meson8b: add the vclk_en gate clock clk: qcom: Fix return value check in apss_ipq6018_probe() clk: bcm: dvp: Add missing module informations clk: meson: meson8b: Drop CLK_IS_CRITICAL from fclk_div2 ...

This was added because we didn't know the relation between this clock and RGMII Ethernet. It turns out that fclk_div2 is used as "timing adjustment clock" to generate the RX delay on the MAC side - which was enabled by u-boot on Odriod-C1. When using the RX delay on the PHY side or not using a RX delay at all then this clock can be disabled.

Otherwise the AHB clk (disp_cc_mdss_ahb_clk_src) for the display clk controller (dispcc) will stop clocking while sourcing from gpll0 when this branch inside GCC is turned off during unused clk disabling. We can never turn this branch off because the AHB clk for the display subsystem is needed to read/write any registers inside the display subsystem including clk related ones. This makes this branch a really easy way to turn off AHB access to the display subsystem and cause all sorts of mayhem. Let's just make the clk ops keep the clk enabled forever and ignore any attempts to disable this clk so that dispcc accesses keep working.
