Once a gdsc is brought in and out of HW control, there is a power down and up cycle which can take upto 1us. Polling on the gdsc status immediately after the hw control enable/disable can mislead software/firmware to belive the gdsc is already either on or off, while its yet to complete the power cycle. To avoid this add a 1us delay post a enable/disable of HW control mode. Also after the HW control mode is disabled, poll on the status to check gdsc status reflects its 'on' before force disabling it in software.

2017-01-23clk: renesas: mstp: Make INTC-SYS a critical clockGeert Uytterhoeven1-0/+5
INTC-SYS is the module clock for the GIC. Accessing the GIC while it is disabled causes: Unhandled fault: asynchronous external abort (0x1211) at 0x00000000 Currently, the GIC-400 driver cannot enable its module clock for several reasons: - It does not use a platform device, so Runtime PM is not an option, - gic_of_init() runs before any clocks are registered, so it cannot enable the clock explicitly, - gic_of_init() cannot return -EPROBE_DEFER, as IRQCHIP_DECLARE() doesn't support deferred probing. Hence we have to keep on relying on the boot loader for enabling the module clock. To prevent the module clock from being disabled when the CCF core thinks it is unused, and thus causing a system lock-up, add a check to the MSTP clock driver and enable CLK_IS_CRITICAL. This will make sure the module clock is never disabled. This is a hard dependency for describing the INTC-SYS clock in DT on R-Mobile APE6 and R-Car Gen2.

When the Renesas CPG/MSSR driver was introduced, it was anticipated that critical clocks would be handled through a new CLK_ENABLE_HAND_OFF flag soon. However, CLK_ENABLE_HAND_OFF never made it upstream. Instead, commit 32b9b10961860860 ("clk: Allow clocks to be marked as CRITICAL") introduced CLK_IS_CRITICAL, a flag with slightly differing semantics. Still, it can be used to prevent e.g. the GIC module clock from being turned off, until the GIC-400 driver has full support for Runtime PM. Hence migrate the Renesas CPG/MSSR driver from CLK_ENABLE_HAND_OFF to CLK_IS_CRITICAL. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Acked-by: Stephen Boyd <sboyd@codeaurora.org>

Add driver for IDT VersaClock 5 5P49V5923 and 5P49V5933 chips. These chips have two clock inputs, XTAL or CLK, which are muxed into single PLL/VCO input. In case of 5P49V5923, the XTAL in built into the chip while the 5P49V5923 requires external XTAL. The PLL feeds two fractional dividers. Each fractional divider feeds output mux, which allows selecting between clock from the fractional divider itself or from output mux on output N-1. In case of output mux 0, the output N-1 is instead connected to the output from the mux feeding the PLL. The driver thus far supports only the 5P49V5923 and 5P49V5933, while it should be easily extensible to the whole 5P49V59xx family of chips as they are all pretty similar.

2017-01-21clk: vc5: Add bindings for IDT VersaClock 5P49V5923 and 5P49V5933Marek Vasut1-0/+65
Add bindings for IDT VersaClock 5 5P49V5923 and 5P49V5933 chips. These are I2C clock generators with optional clock source from either XTal or dedicated clock generator and, depending on the model, two or more clock outputs.

The LDB mux/gate layout has been fixed on QuadPlus, so there is no need to restrict the LDB mux changes on this hardware, as the erratum preventing this from working properly is gone.
