ARM: tegra: Tegra114 pinmux cleanup

2014-04-17T15:41:06Z

This renames all the pinmux pins, drive groups, and functions so they have a prefix which matches the type name. These lists are also auto- generated using scripts that were also used to generate the kernel pinctrl drivers. This ensures that the lists are consistent between the two. The entries in tegra114_pingroups[] are all updated to remove the columns which are no longer used. All affected code is updated to match. This introduces a few changes to pin/group/function naming and the set of available functions for each pin. The new values now exactly match the TRM; the chip documentation. I adjusted a few entries in pinmux-config-dalmore.h due to this. Signed-off-by: Stephen Warren Signed-off-by: Tom Warren

ARM: tegra: pinmux naming consistency fixes

2014-04-17T15:41:05Z

Clean up the naming of pinmux-related objects: * Refer to drive groups rather than pad groups to match the Linux kernel. * Ensure all pinmux API types are prefixed with pmux_, values (defines) are prefixed with PMUX_, and functions prefixed with pinmux_. * Modify a few type names to make their content clearer. * Minimal changes to SoC-specific .h/.c files are made so the code still compiles. A separate per-SoC change will be made immediately following, in order to keep individual patch size down. Signed-off-by: Stephen Warren Acked-by: Simon Glass Signed-off-by: Tom Warren

ARM: tegra: make all I2C ports open-drain

2014-03-26T22:20:56Z

I2C protocol requires open-drain IOs. Fix the Dalmore and Venice2 pinmux tables to configure the IOs correctly. Without this, Tegra may actively drive the lines high while an external device is actively driving the lines low, which can only lead to bad things.

Tegra114: MMC: Add SD bus power-rail init routine

Tegra114: Dalmore: Add SDIO3 pad config to pinctrl_config table

2013-03-25T16:56:07Z

SDIO1 (the SD-card slot on Dalmore) needs to have its pads setup before the MMC driver is added. Signed-off-by: Tom Warren Reviewed-by: Stephen Warren

Tegra114: Dalmore: Add pad config tables/code based on pinmux code

2013-03-14T18:49:14Z

Pad config registers exist in APB_MISC_GP space, and control slew rate, drive strengh, schmidt, high-speed, and low-power modes for all of the pingroups in Tegra30. This builds off of the pinmux way of constructing init tables to configure select pads (SDIOCFG, for instance) during pinmux_init(). Currently, no padcfg entries exist. SDIO3CFG will be added when the MMC driver is added as per the TRM to work with the SD-card slot on Dalmore E1611. Signed-off-by: Tom Warren Reviewed-by: Stephen Warren

Tegra114: Dalmore: Always use DEFAULT instead of DISABLE for lock bits

2013-03-14T18:48:55Z

The pinmux code issues a warning if the caller attempts to disable the lock bit in a pinmux register, since this is impossible (once it's locked, the only way to unlock it is to reset the device/pmt controller). The I2C/DDC/CEC/USB macros expect a lock setting to be passed in, and the previous setting of DISABLE caused the pinmux table parsing code to issue the warning. Changing the lock bits in these table entries to DEFAULT (i.e. don't touch it) fixes this. Signed-off-by: Tom Warren Reviewed-by: Stephen Warren

Tegra114: pinmux: Update pinmux tables & code, fix a bug w/SDMMC3 init

2013-03-14T18:06:43Z

Use the latest tables & code from our internal U-Boot repo. The SDMMC3_CD, CLK_LB_IN and CLK_LB_OUT offsets in the pingroup table were off by a few indices, causing the pinmux init code to write bad data to the PINMUX_AUX_ regs. This also enabled the lock bit, which made it impossible to reconfig the pads correctly for SDMMC3 (SD card on Dalmore) operation. Also fixes SPI_CS2_N, USB_VBUS_EN0, HDMI_CEC and UART2_RXD/TXD muxes. Signed-off-by: Tom Warren Reviewed-by: Stephen Warren
