2023-07-19clk: renesas: rzg2l: Fix CPG_SIPLL5_CLK1 register writeBiju Das2-7/+2
[ Upstream commit d1c20885d3b01e6a62e920af4b227abd294d22f3 ] As per the RZ/G2L HW(Rev.1.30 May2023) manual, there are no "write enable" bits in the CPG_SIPLL5_CLK1 register. So fix the CPG_SIPLL5_CLK register write by removing the "write enable" bits.

2023-03-17clk: renesas: rcar-gen3: Disable R-Car H3 ES1.*Wolfram Sang5-173/+13
[ Upstream commit b1dec4e78599a2ce5bf8557056cd6dd72e1096b0 ] R-Car H3 ES1.* was only available to an internal development group and needed a lot of quirks and workarounds. These become a maintenance burden now, so our development group decided to remove upstream support for this SoC. Public users only have ES2 onwards. In addition to the ES1 specific removals, a check for it was added preventing the machine to boot further. It may otherwise inherit wrong clock settings from ES2 which could damage the hardware.

As per RZ/G2L HW(Rev.1.10) manual, reset monitor register value 0 means reset signal is not applied (deassert state) and 1 means reset signal is applied (assert state). reset_control_status() expects a positive value if the reset line is asserted. But rzg2l_cpg_status function returns zero for asserted state.

2022-05-19clk: renesas: r9a06g032: Probe possible childrenMiquel Raynal1-0/+5
The clock controller device on r9a06g032 takes all the memory range that is described as being a system controller. This range contains many different (unrelated?) registers besides the ones belonging to the clock controller, that can necessitate to be accessed from other peripherals. For instance, the dmamux registers are there. The dmamux "device" will be described as a child node of the clock/system controller node, which means we need the top device driver (the clock controller driver in this case) to populate its children manually. In case of error when populating the children, we do not fail the probe on purpose to keep the clk driver up and running.
