soc/tegra: pmc: Remove some old and deprecated functions and constants

2024-02-01T14:58:04Z

These TEGRA_IO_RAIL_... functions and constants have been deprecated in commit 21b499105178 ("soc/tegra: pmc: Add I/O pad voltage support") in 2016-11. There seems to be no users since kernel 4.16. Remove them now. Signed-off-by: Christophe JAILLET Signed-off-by: Thierry Reding

soc/tegra: pmc: Add I/O pad table for Tegra234

2022-11-10T01:21:12Z

Add I/O pad table for Tegra234 to allow configuring DPD mode and switching the pins to 1.8V or 3.3V as needed. On Tegra234, DPD registers are reorganized such that there is a DPD_REQ register and a DPD_STATUS register per pad group. Update the PMC driver accordingly. While at it, use the generated tables from tegra-pinmux-scripts to make the formatting of these tables more consistent.

soc/tegra: pmc: Add driver state syncing

2021-06-02T08:58:55Z

Add driver state syncing that is invoked once all PMC consumers are attached and ready. The consumers are the power domain clients. The synchronization callback is invoked once all client drivers are probed, the driver core handles this for us. This callback informs PMC driver that all voltage votes are initialized by each PD client and it's safe to begin voltage scaling of the core power domain.

soc/tegra: pmc: Add pins for Tegra194

2020-03-13T09:53:10Z

Extend the Tegra194 IO pad table with additional information such as pin names and 1.8/3.3 V settings to allow a table of voltage control pins to generated from it. This is similar to what's done for older chips and is needed to support high-speed modes for SDHCI where switching the pins to 1.8V or 3.3V is necessary.
