* clk: tegra: Mark fuse clock as criticalStephen Warren2020-01-081-1/+5
| | | | | | | | | | | | | | | | | For a little over a year, U-Boot on Tegra124 has configured the flow controller to perform automatic RAM re-repair on off->on power transitions of the CPU rail[1]. This is mandatory for correct operation of Tegra124. However, RAM re-repair relies on certain clocks, which the kernel must enable and leave running. The fuse clock is one of those clocks. Mark this clock as critical so that LP1 power mode (system suspend) operates correctly.

* clk: tegra: Move SOR0 implementation to Tegra124Thierry Reding2019-11-111-8/+0
| | | | | | | | | | The SOR0 clock on Tegra210 is very different from the SOR0 clock found on Tegra124. Move the Tegra124 implementation to the Tegra124 driver so that a custom implementation can be provided on Tegra210 without clashing with the existing clock.

* clk: tegra: Fix sor1_out clock implementationThierry Reding2017-10-191-16/+0
| | | | | | | | | | | | | This clock was previously called sor1_src and was modelled as an input to the sor1 module clock. However, it's really an output clock that can be fed either from the safe, the sor1_pad_clkout or the sor1 module clocks. sor1 itself can take input from either of the display PLLs. The same implementation for the sor1_out clock is used on Tegra186, so this nicely lines up both SoC generations to deal with this clock in a uniform way.

* clk: tegra: Mark timer clock as criticalThierry Reding2016-06-221-1/+1
| | | | | | | | | | | | | | | The timer clock feeds the timer block, which, among other things, is used to drive the SOR lane sequencer. Since the Tegra timer driver is not enabled on 64-bit ARM, nothing currently claims that clock and it gets disabled by the common clock framework at late_init time. Given the non-obvious dependencies, the timer clock can be considered a critical part of the SoC infrastructure, requiring its clock source to be always on.

* clk: tegra: Squash sor1 safe/brick/src into a single muxThierry Reding2016-06-171-11/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sor1 clock on Tegra210 is structured in the following way: +-------+ | pllp |---+ +-------+ | +--------------+ +-----------+ +----| | | sor_safe | +-------+ | | +-----------+ | plld |--------| | | +-------+ | | +-----------+ | sor1_src |-------| | +-------+ | | +-----------+ | plld2 |--------| | | +-------+ | | | +----| | | +-------+ | +--------------+ | | clkm |---+ +-----------+ +-------+ +--------------+ | | | sor1_brick |-------| sor1 | +--------------+ | | +-----------+ This is impractical to represent in a clock tree, though, because there is no name for the mux that has sor_safe and sor1_src as parents. It is also much more cumbersome to deal with the additional mux because users of these clocks (the display driver) would have to juggle with an extra mux for no real reason. To simply things, the above is squashed into two muxes instead, so that it looks like this: +-------+ | pllp |---+ +-------+ | +--------------+ +-----------+ +----| | | sor_safe | +-------+ | | +-----------+ | plld |--------| | | +-------+ | | +-----------+ | sor1_src |-------| sor1 | +-------+ | | +-----------+ | plld2 |--------| | | | +-------+ | | | | +----| | | | +-------+ | +--------------+ | | | clkm |---+ | | +-------+ +--------------+ | | | sor1_brick |-----------+---+ +--------------+ This still very accurately represents the hardware. Note that sor1 has sor1_brick as input twice, that's because bit 1 in the mux selects the sor1_brick irrespective of bit 0. Signed-off-by: Thierry Reding <treding@nvidia.com>

| | | | | | | | | | | | | | | | | | | | | Tegra210 has significant differences in muxes for peripheral clocks. One of the most important changes is that pll_m isn't to be used as a source for peripherals. Therefore, we need to define the new muxes and new clocks to use those muxes for Tegra210 support. Tegra210 has some differences in the PLLP clock tree: - Four new output clocks: PLLP_OUT_CPU, PLLP_OUT_ADSP, PLLP_OUT_HSIO, and PLLP_OUT_XUSB. - PLLP_OUT2 is fixed at 1/2 the rate of PLLP_VCO. - PLLP_OUT4 is the child of PLLP_OUT_CPU.
