* ARM: tegra: Tegra114 pinmux cleanupStephen Warren2014-04-17-236/+223
| | | | | | | | | | | | | | | | | | | | | 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 <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
* ARM: tegra: pinmux naming consistency fixesStephen Warren2014-04-17-2/+2
| | | | | | | | | | | | | | | 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.

* ARM: tegra: pinctrl: remove duplicationStephen Warren2014-04-17-428/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Much of arch/arm/cpu/tegra*-common/pinmux.c is identical. Remove the duplication by creating pinmux-common.c for all the identical code. This leaves: * arch/arm/include/asm/arch-tegra*/pinmux.h defining only the names of the various pins/pin groups, drive groups, and mux functions. * arch/arm/cpu/tegra*-common/pinmux.c containing only the lookup table stating which pin groups support which mux functions. The code in pinmux-common.c is semantically identical to that in the various original pinmux.c, but had some consistency and cleanup fixes applied during migration. I removed the definition of struct pmux_tri_ctlr, since this is different between SoCs (especially Tegra20 vs all others), and it's much simpler to deal with this via the new REG/MUX_REG/... defines. spl.c, warmboot.c, and warmboot_avp.c needed updates due to this, since they previously hijacked this struct to encode the location of some non-pinmux registers. Now, that code simply calculates these register addresses directly using simple and obvious math. I like this method better irrespective of the pinmux code cleanup anyway.

Note that PIN() macros are left unchanged for now, to avoid many diffs to them; later commits will completely rewrite them just one time.

* Tegra114: Dalmore: Add pad config tables/code based on pinmux codeTom Warren2013-03-14-0/+194
| | | | | | | | | | | | | | | 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.

* Tegra114: pinmux: Fix bad CAM_MCLK func 3 table entryTom Warren2013-03-14-1/+1
| | | | | | | | This caused CAM_MCLK's pinmux reg to be locked out, since the table parsing code couldn't find a matching entry for VI_ALT3 and wrote garbage to the register. Signed-off-by: Tom Warren <twarren@nvidia.com>
* Tegra114: pinmux: Update pinmux tables & code, fix a bug w/SDMMC3 initTom Warren2013-03-14-87/+127
| | | | | | | | | | | | | 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 <twarren@nvidia.com> Reviewed-by: Stephen Warren <swarren@nvidia.com>
