clk: renesas: rcar-gen3: Update description for RZ/G2

2020-09-17T13:32:25Z

The rcar-gen3-cpg driver is also used on Renesas RZ/G2 SoC's, update the description for the CLK_RCAR_GEN3_CPG config symbol to reflect this.

clk: renesas: cpg-mssr: Add support for R-Car V3U

2020-09-17T13:32:25Z

Initial support for R-Car V3U (r8a779a0), including core, module clocks, resets, and register access, because register specification differs from R-Car Gen2/3. Inspired by patches in the BSP by LUU HOAI.

clk: renesas: cpg-mssr: Add register pointers into struct cpg_mssr_priv

2020-09-17T13:30:08Z

To support other register layouts in the future, add register pointers of {control,status,reset,reset_clear}_regs into struct cpg_mssr_priv. After that, we can remove unused macros like MSTPSR(). No behavioral changes. Signed-off-by: Yoshihiro Shimoda Link: https://lore.kernel.org/r/1599810232-29035-3-git-send-email-yoshihiro.shimoda.uh@renesas.com Signed-off-by: Geert Uytterhoeven

clk: renesas: cpg-mssr: Use enum clk_reg_layout instead of a boolean flag

2020-09-17T13:30:08Z

Geert suggested defining multiple register layout variants using an enum [1] to support further devices like R-Car V3U. So, use enum clk_reg_layout instead of a boolean .stbyctrl flag. No behavioral change.

clk: renesas: rcar-gen2: Rename vsp1-(sy|rt) clocks to vsp(s|r)

2020-09-04T07:42:01Z

VSP1 instances VSPS (which stands for "VSP Standard") and VSPR (which stands for "VSP for Resizing") were wrongly named as "vsp1-sy" and "vsp1-rt". The clock section in the SoC datasheets misunderstood the abbreviations as meaning VSP System and VSP Realtime, and named the corresponding clocks VSP1(SY) and VSP1(RT). This mistake has been carried over to the kernel code. This patch fixes this by renaming the clock names to "vsps" and "vspr".

clk: renesas: r8a7742: Add clk entry for VSPR

2020-09-04T07:42:01Z

Add clock entry 130 for VSPR (VSP for Resizing) module, so that this module can be used on R8A7742 (RZ/G1H) SoC. Alongside rename clock entry "vsp1-sy" to "vsps" (VSP Standard), so that VSP1 clock names are in sync. Note: The entry for VSPR clock was accidentally dropped from RZ/G manual when all the information related to RT were removed.

clk: renesas: cpg-mssr: Mark clocks as critical only if on at boot

2020-06-22T14:53:40Z

This allows us to add the RWDT clock to the list of critical clocks without keeping it enabled needlessly if not used. Changing the semantics of crit_mod_clks in this way is safe for the current user (INTC-AP) because it is never off at boot time.
