[U-Boot] [PATCH] tegra: pinmux: fix FUNCMUX_NDFLASH_KBC_8_BIT
by Lucas Stach 23 Jan '13

23 Jan '13

Even the 8bit case needs KBCB configured, as pin D7 is located in this pingroup. Also pingroup ATC seems to come out of reset with config set to NAND, so we need to explictly configure some other function to this group in order to avoid clashing settings.

[U-Boot] [PATCH] tegra: implement pinmux_avoid_func()
by Stephen Warren 23 Jan '13

23 Jan '13

From: Stephen Warren <swarren(a)nvidia.com> This selects the "safe" (non-conflicting) mux function for a pin group if the current setting matches the specified function. Many signals can be routed to or from multiple different groups. Each signal must be routed to or from only a single group at a given time. Hence, if we program a particular group for a function, we must ensure no other group is programmed to that same function first. This API makes this easy. Signed-off-by: Stephen Warren <swarren(a)nvidia.com> --- This patch will need updating due to the recently added Tegra30 support. However, I'm posting it for Lucas, since his NAND patches can probably benefit from this. arch/arm/cpu/tegra20-common/pinmux.c | 23 +++++++++++++++++++++++ arch/arm/include/asm/arch-tegra20/pinmux.h | 6 ++++++ 2 files changed, 29 insertions(+) diff --git a/arch/arm/cpu/tegra20-common/pinmux.c b/arch/arm/cpu/tegra20-common/pinmux.c index 5ad2121..47179f3 100644 --- a/arch/arm/cpu/tegra20-common/pinmux.c +++ b/arch/arm/cpu/tegra20-common/pinmux.c @@ -554,6 +554,29 @@ void pinmux_set_func(enum pmux_pingrp pin, enum pmux_func func) writel(reg, muxctl); } +static enum pmux_func pinmux_get_func(enum pmux_pingrp pin) +{ + struct pmux_tri_ctlr *pmt = + (struct pmux_tri_ctlr *)NV_PA_APB_MISC_BASE; + enum pmux_ctlid mux_id = tegra_soc_pingroups[pin].ctl_id; + u32 *muxctl = &pmt->pmt_ctl[MUXCTL_REG(mux_id)]; + u32 reg; + + reg = readl(muxctl); + reg >>= MUXCTL_SHIFT(mux_id); + reg &= 3; + + return tegra_soc_pingroups[pin].funcs[reg]; +} + +void pinmux_avoid_func(enum pmux_pingrp pin, enum pmux_func avoid) +{ + if (pinmux_get_func(pin) != avoid) + return; + + pinmux_set_func(pin, tegra_soc_pingroups[pin].func_safe); +} + void pinmux_config_pingroup(const struct pingroup_config *config) { enum pmux_pingrp pin = config->pingroup; diff --git a/arch/arm/include/asm/arch-tegra20/pinmux.h b/arch/arm/include/asm/arch-tegra20/pinmux.h index a9b4eda..d36e18e 100644 --- a/arch/arm/include/asm/arch-tegra20/pinmux.h +++ b/arch/arm/include/asm/arch-tegra20/pinmux.h @@ -337,6 +337,12 @@ void pinmux_set_pullupdown(enum pmux_pingrp pin, enum pmux_pull pupd); /* Set the mux function for a pin group */ void pinmux_set_func(enum pmux_pingrp pin, enum pmux_func func); +/* + * Select the "safe" (non-conflicting) mux function for a pin group if the + * current setting matches the specified function. + */ +void pinmux_avoid_func(enum pmux_pingrp pin, enum pmux_func func); + /* Set the complete configuration for a pin group */ void pinmux_config_pingroup(const struct pingroup_config *config); -- 1.7.10.4

[U-Boot] [PATCH v2 0/7] Add support for NVIDIA Tegra114 SoC
by Tom Warren 22 Jan '13

22 Jan '13

This patch series adds basic (boot to cmd prompt) support for Tegra114. This is based on the Tegra30 SPL, which inits the AVP (ARM7TDMI boot proc) first, then control is passed to the CPU (A15 quad cluster). It is based on current u-boot-tegra/next. Future patches will add support/drivers for I2C, SPI, MMC, USB, etc. The Dalmore (E1611) T114 board is supported initially. Changes in v2: - Rework patchset as per feedback from Stephen and Allen. Tom Warren (7): Tegra114: Add arch-tegra114 include files Tegra114: Add AVP (arm720t) files Tegra114: Add CPU (armv7) files Tegra114: Add common CPU (shared) files Tegra114: Dalmore: Add DT files Tegra114: Add generic Tegra114 build support Tegra114: Add/enable Dalmore build (T114 reference board) arch/arm/cpu/arm720t/tegra-common/cpu.c | 75 +- arch/arm/cpu/arm720t/tegra-common/cpu.h | 8 +- arch/arm/cpu/arm720t/tegra114/Makefile | 42 + arch/arm/cpu/arm720t/tegra114/config.mk | 19 + arch/arm/cpu/arm720t/tegra114/cpu.c | 315 ++++++ arch/arm/cpu/armv7/tegra114/Makefile | 40 + arch/arm/cpu/armv7/tegra114/config.mk | 19 + arch/arm/cpu/tegra-common/ap.c | 9 +- arch/arm/cpu/tegra-common/board.c | 21 +- arch/arm/cpu/tegra114-common/Makefile | 41 + arch/arm/cpu/tegra114-common/clock.c | 1150 +++++++++++++++++++++ arch/arm/cpu/tegra114-common/funcmux.c | 63 ++ arch/arm/cpu/tegra114-common/pinmux.c | 506 +++++++++ arch/arm/dts/tegra114.dtsi | 5 + arch/arm/include/asm/arch-tegra/clk_rst.h | 58 +- arch/arm/include/asm/arch-tegra/gp_padctrl.h | 1 + arch/arm/include/asm/arch-tegra/pmc.h | 12 + arch/arm/include/asm/arch-tegra/tegra.h | 3 + arch/arm/include/asm/arch-tegra114/clock-tables.h | 402 +++++++ arch/arm/include/asm/arch-tegra114/clock.h | 28 + arch/arm/include/asm/arch-tegra114/flow.h | 35 + arch/arm/include/asm/arch-tegra114/funcmux.h | 31 + arch/arm/include/asm/arch-tegra114/gp_padctrl.h | 59 ++ arch/arm/include/asm/arch-tegra114/gpio.h | 30 + arch/arm/include/asm/arch-tegra114/hardware.h | 22 + arch/arm/include/asm/arch-tegra114/pinmux.h | 618 +++++++++++ arch/arm/include/asm/arch-tegra114/pmu.h | 23 + arch/arm/include/asm/arch-tegra114/spl.h | 22 + arch/arm/include/asm/arch-tegra114/tegra.h | 31 + arch/arm/include/asm/arch-tegra20/clock.h | 4 + arch/arm/include/asm/arch-tegra30/clock.h | 4 + board/nvidia/common/board.c | 2 +- board/nvidia/dalmore/Makefile | 36 + board/nvidia/dalmore/dalmore.c | 32 + board/nvidia/dalmore/pinmux-config-dalmore.h | 249 +++++ board/nvidia/dts/tegra114-dalmore.dts | 13 + boards.cfg | 1 + include/configs/dalmore.h | 50 + include/configs/tegra114-common.h | 79 ++ 39 files changed, 4108 insertions(+), 50 deletions(-) create mode 100644 arch/arm/cpu/arm720t/tegra114/Makefile create mode 100644 arch/arm/cpu/arm720t/tegra114/config.mk create mode 100644 arch/arm/cpu/arm720t/tegra114/cpu.c create mode 100644 arch/arm/cpu/armv7/tegra114/Makefile create mode 100644 arch/arm/cpu/armv7/tegra114/config.mk create mode 100644 arch/arm/cpu/tegra114-common/Makefile create mode 100644 arch/arm/cpu/tegra114-common/clock.c create mode 100644 arch/arm/cpu/tegra114-common/funcmux.c create mode 100644 arch/arm/cpu/tegra114-common/pinmux.c create mode 100644 arch/arm/dts/tegra114.dtsi create mode 100644 arch/arm/include/asm/arch-tegra114/clock-tables.h create mode 100644 arch/arm/include/asm/arch-tegra114/clock.h create mode 100644 arch/arm/include/asm/arch-tegra114/flow.h create mode 100644 arch/arm/include/asm/arch-tegra114/funcmux.h create mode 100644 arch/arm/include/asm/arch-tegra114/gp_padctrl.h create mode 100644 arch/arm/include/asm/arch-tegra114/gpio.h create mode 100644 arch/arm/include/asm/arch-tegra114/hardware.h create mode 100644 arch/arm/include/asm/arch-tegra114/pinmux.h create mode 100644 arch/arm/include/asm/arch-tegra114/pmu.h create mode 100644 arch/arm/include/asm/arch-tegra114/spl.h create mode 100644 arch/arm/include/asm/arch-tegra114/tegra.h create mode 100644 board/nvidia/dalmore/Makefile create mode 100644 board/nvidia/dalmore/dalmore.c create mode 100644 board/nvidia/dalmore/pinmux-config-dalmore.h create mode 100644 board/nvidia/dts/tegra114-dalmore.dts create mode 100644 include/configs/dalmore.h create mode 100644 include/configs/tegra114-common.h
