* clk: tegra: Fix maximum audio sync clock for Tegra124/210Jon Hunter2018-12-141-2/+2
| | | | | | | | | | | | | | | | | | The maximum frequency supported for I2S on Tegra124 and Tegra210 is 24.576MHz (as stated in the Tegra TK1 data sheet for Tegra124 and the Jetson TX1 module data sheet for Tegra210). However, the maximum I2S frequency is limited to 24MHz because that is the maximum frequency of the audio sync clock. Increase the maximum audio sync clock frequency to 24.576MHz for Tegra124 and Tegra210 in order to support 24.576MHz for I2S. Update the tegra_clk_register_sync_source() function so that it does not set the initial rate for the sync clocks and use the clock init tables to set the initial rate instead.

* clk: tegra: Add sdmmc mux divider clockPeter De-Schrijver2018-07-251-0/+26
| | | | | | | | | | | | | | | Add a clock type to model the sdmmc switch divider clocks which have paths to source clocks bypassing the divider (Low Jitter paths). These are handled by selecting the lj path when the divider is 1 (ie the rate is the parent rate), otherwise the normal path with divider will be selected. Otherwise this clock behaves as a normal peripheral clock.

* clk: tegra: Add quirk for getting CDEV1/2 clocks on Tegra20Dmitry Osipenko2018-05-181-1/+1
| | | | | | | | | | | | | CDEV1 and CDEV2 clocks are a bit special case, their parent clock is created by the pinctrl driver. It should be possible for clk user to request these clocks before pinctrl driver got probed and hence user will get an orphaned clock. That might be undesirable because user may expect parent clock to be enabled by the child, so let's return -EPROBE_DEFER till parent clock appears.

* clk: tegra: Initialize UTMI PLL when enabling PLLUAndrew Bresticker2016-06-301-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the UTMI PLL initialization code form clk-tegra<chip>.c files into clk-pll.c. UTMI PLL was being configured and set in HW control right after registration. However, when the clock init_table is processed and child clks of PLLU are enabled, it will call in and enable PLLU as well, and initiate SW enabling sequence even though PLLU is already in HW control. This leads to getting UTMIPLL stuck with a SEQ_BUSY status. Doing the initialization once during pllu_enable means we configure it properly into HW control. A side effect of the commonization/localization of the UTMI PLL init code, is that it corrects some errors that were present for earlier generations. For instance, in clk-tegra124.c, it used to have: #define UTMIP_PLL_CFG1_ENABLE_DLY_COUNT(x) (((x) & 0x1f) << 6) when the correct shift to use is present in the new version: #define UTMIP_PLL_CFG1_ENABLE_DLY_COUNT(x) (((x) & 0x1f) << 27) which matches the Tegra124 TRM register definition.

* clk: tegra: Model oscillator as clockThierry Reding2015-04-101-4/+4
| | | | | | | | | | | | | | | | Currently the Tegra clock driver simplifies the clock tree somewhat by taking advantage of the fact that clk_m runs at the same frequency as the oscillator. While that's true on all currently supported SoCs, it does not apply to Tegra210 anymore. On Tegra210 clk_m is typically divided down from the oscillator frequency. To support that setup, add a separate clock for the oscillator that both clk_m and pll_ref derive from. Modify the tegra_osc_clk_init() function to take an additional divider parameter for clk_m. Existing SoCs always pass in 1, whereas Tegra210 will read the divider from a register in the clock & reset controller. Signed-off-by: Thierry Reding <treding@nvidia.com>
