2017-04-12clk: zte: pd_bit is not 0 on zx296718Shawn Guo2-2/+16
The bit 0 of PLL_CFG0 register is not powerdown on zx296718, but part of of postdiv2 field. The consequence is that functions like hw_to_idx() and zx_pll_enable() will end up tampering the postdiv2 of the PLL. Let's fix it by defining pd_bit 0xff which is obviously invalid for a bit position and having PLL driver check the validity before operating on the bit.

2017-04-12clk: zte: set CLK_SET_RATE_PARENT for a few zx296718 clocksShawn Guo1-3/+3
To support VOU VGA display driver with different modes, we need to set flag for a few clocks, so that clk_set_rate() call in VOU driver can get VGA device desired pixel rate. While at it, the divider between pll_vga and clk_vga gets corrected, as it's 1:1 instead of 1:2.

Contains some new clock-ids as well as fixups of the clock-ids on rk3368 timers, which were unused and completely wrong (more and differently named timers). Also there is one new clock on rk3328 using the muxgrf type, a fix for pll enablement which should wait for the pll to lock before continuing, some more critical clocks and the rename of the rk1108 to rv1108, as the soc seems to have been using a preliminary name before its actual release. The plan is to have the driver changes (pinctrl, clk) go through the respective maintainer trees and once everything landed in mainline do the rename of the devicetree files. With the dts-include change in the clock rename, we also keep everything compiling and thus bisectability. * tag 'v4.12-rockchip-clk1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip: clk: rockchip: add pll_wait_lock for pll_enable clk: rockchip: rename RK1108 to RV1108 dt-bindings: rk1108-cru: rename RK1108 to RV1108 clk: rockchip: mark some rk3368 core-clks as critical clk: rockchip: export SCLK_TIMERXX id for timers on rk3368 clk: rockchip: describe clk_gmac using the new muxgrf type on rk3328 clk: rockchip: add clock ids for timer10-15 of RK3368 SoCs clk: rockchip: fix up rk3368 timer-ids clk: rockchip: add rk3328 clk_mac2io_ext ID clk: rockchip: Set "ignore unused" for PMU M0 clocks on rk3399

2017-04-04clk: tegra: Don't reset PLL-CX if it is already enabledJon Hunter1-4/+4
Commit 8dce89a1c2cf ("clk: tegra: Don't warn for PLL defaults unnecessarily") changed the tegra210_pllcx_set_defaults() function causing the PLL to always be reset regardless of whether it is in-use. This function was changed so that resetting of the PLL will only be skipped if the PLL is enabled AND 'pllcx->params->defaults_set' is not true. However, the 'pllcx->params->defaults_set' is always true and hence, the PLL is now always reset. This causes the boot to fail on the Tegra210 Smaug where the PLL is already enabled and in-use. Fix this by only resetting the PLL if not in-use and only printing the warning that the defaults are not set after we have checked the default settings.

2017-03-30clk: renesas: r8a7795: Add support for R-Car H3 ES2.0Geert Uytterhoeven1-50/+151
The Clock Pulse Generator / Module Standby and Software Reset module in R-Car H3 ES2.0 differs from ES1.x in the following areas: - More core clocks (S0D2, S0D3, S0D6, S0D8, S0D12), - Different parent clocks for AUDMAC, EtherAVB, FCP, FDP, IMR, SYS-DMAC, VIN, VSPB, VSPI, - Removal of modules CSI21, FCPCI, FCPF2, FCPVD3, FCPVI2, FDP1-2, USB3-IF1, VSPD3, VSPI2, - Addition of modules EHCI3, HS-USB-IF3, USB-DMAC3-0, USB-DMAC3-1. The goal is twofold: 1. Support both the ES1.x and ES2.0 SoC revisions in a single binary for now, 2. Make it clear which code supports ES1.x, so it can easily be identified and removed later, when production SoCs are deemed ubiquitous. This is achieved by: - Updating the clock tables for the latest revision (ES2.0), but not removing clocks that only exist on earlier revisions (ES1.x), - Detecting the SoC revision at runtime using the new soc_device_match() API, and fixing up the clocks tables to match the actual SoC revision, by: - NULLifying core and module clocks of modules that do not exist, - Reparenting module clocks that have a different parent on ES1.x. Based on R-Car Gen3 Hardware User's Manual rev. 0.53E. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
2017-03-30clk: renesas: cpg-mssr: Add support for fixing up clock tablesGeert Uytterhoeven2-0/+72
The same SoC may have different clocks and/or module clock parents, depending on SoC revision. One option is to use different sets of clock tables for each SoC revision. However, if the differences are small, it is much more space-efficient to have a single set of clock tables, and fix those up at runtime instead. Hence provide three helpers: - Two helpers to NULLify core and module clocks that do not exist on some revisions (NULLified clocks are skipped during the registration phase), - One helper to reparent module clocks that have different clock parents.

2017-03-20clk: tegra: Rework pll_uPeter De Schrijver2-197/+272
In normal operation pll_u is under hardware control and has a fixed rate of 480MHz. Hardware will turn on pll_u on whenever any of the XUSB powerdomains is on. From a software point of view we model this is if pll_u is always on using a fixed rate clock. However the bootloader might or might not have configured pll_u this way. So we will check the current state of pll_u at boot and reconfigure it if required. There are 3 possiblities at kernel boot: 1) pll_u is under hardware control: do nothing 2) pll_u is under hardware control and enabled: enable hardware control 3) pll_u is disabled: enable pll_u and enable hardware control In all cases we also check if UTMIPLL is under hardware control at boot and configure it for hardware control if that is not the case.

Return the actually achieved rate in cfg->output_rate rather than just the requested rate. This is important to make clk_round_rate() return the correct result.

The parent for afi is actually mselect, not clk_m. Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com> Reviewed-by: Mikko Perttunen <mperttunen@nvidia.com> Tested-by: Mikko Perttunen <mperttunen@nvidia.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2017-03-20clk: tegra: Fix ISP clock modellingPeter De Schrijver3-2/+11
The 2 ISP clocks (ispa and ispb) share a mux/divider control. So model this as 1 mux/divider clock and child gate clocks.
