[U-Boot] [PATCH] ARM: vexpress: Remove virt and nonsec support for TC2
by Jon Medhurst (Tixy) 16 Aug '16

16 Aug '16

When CPU's come out of reset they are in secure state supervisor mode, so this is the state Linux kernel entry point is called in when it brings up secondary CPU cores or the primary CPU restarts after power management has sent it through an off/on transition. As U-Boot starts the kernel in hypervisor mode and the kernel expects and checks that CPUs start in the same state as initial boot this results in a dead system. Specifically, it crashes early in boot when the primary CPU runs the MCPM test [1] and even if power management features are disabled it will still refuse to bring up any secondary CPUs. Fix this problem by removing U-Boot support for virt and nonsec support on TC2.

The __get_unaligned_le* functions may not be declared on all platforms. Instead, get_unaligned_le* should be used. On many platforms both of these are the same function.

[U-Boot] [PATCH v7 0/4] ARM: AT91: Add AT91 PIO4 pinctrl driver and gpio driver with DM
by Wenyou Yang 15 Aug '16

15 Aug '16

AT91 PIO4 controller is a combined gpio-controller, pin-mux and pin-config module. This patch is to add the pinctrl driver, and rework the atmel-pio4 gpio driver to support driver model and device tree. Changes in v7: - Change clk_client.h -> clk.h to adapt to clk API conversion. - Drop [PATCH]: configs: sama5d2_xplained: Add #ifndef before CONFIG_ATMEL_PIO4. Changes in v6: - Add Reviewed-by tag. - Fixed the return value, -EINVAL -> ret. Changes in v5: - Update the clk API based on [PATCH] clk: convert API to match reset/mailbox fstyle (http://patchwork.ozlabs.org/patch/625342/). - Use clrbits_le32() to replace readl()/writel(). - Fixed the return value, -ENODEV->-EINVAL. - Remove check on dev_get_parent() return. - Fixed the return value, -ENODEV->-EINVAL. - Remove check on dev_get_parent() return. Changes in v4: - Remove the redundant log print. Changes in v3: - Add bind callback to support the pinctl device regarding as a child of atmel_pio4 device. - Add clock support. - Rework due to the pinctrl device is regarded as atmel_pio4 device's child. Changes in v2: - remove meaningless comment. - add else path for argument of pinconf. - add inline attribute for atmel_pio4_bank_base(). - add handle if the pinmux entries is greater maximum value. - add detailed example to show how to configure pinctrl for device. - remove interrupt and gpio property description. - add reviewed-by tag.

Changes in v4: - Add Reviewed-by tag. - Add more information in Kconfig help. - Use u32 for num_parents variable, not u8. - Change the check return from clk_get_rate(). - Remove return -ENODEV line, use return ret. - Improve the comments in at91_system_clk_enable(). Changes in v3: - Update based on [PATCH] clk: convert API to match reset/mailbox style (http://patchwork.ozlabs.org/patch/625342/). - Remove [PATCH] clk: clk-uclass: Add post binding for CLK uclass, add bind() method to bind the clk node without compatible. - Add help for Kconfig HAVE_AT91_XX option. - Add ofdata_to_platdata() method for generated clock driver to handle the device tree. - Use setbits_le32() to replace readl()/writel(). - Fixed the return value, -ENODEV->-EINVAL. - Use dev_get_addr_ptr() to replace dev_get_addr(). - Remove check on dev_get_parent() return. Changes in v2: - Remove the redundant log print. arch/arm/mach-at91/include/mach/at91_pmc.h | 11 +- drivers/clk/Kconfig | 1 + drivers/clk/Makefile | 1 + drivers/clk/at91/Kconfig | 43 ++++++++ drivers/clk/at91/Makefile | 11 ++ drivers/clk/at91/clk-generated.c | 162 +++++++++++++++++++++++++++++ drivers/clk/at91/clk-h32mx.c | 56 ++++++++++ drivers/clk/at91/clk-main.c | 55 ++++++++++ drivers/clk/at91/clk-master.c | 33 ++++++ drivers/clk/at91/clk-peripheral.c | 60 +++++++++++ drivers/clk/at91/clk-plla.c | 55 ++++++++++ drivers/clk/at91/clk-slow.c | 37 +++++++ drivers/clk/at91/clk-system.c | 76 ++++++++++++++ drivers/clk/at91/clk-utmi.c | 67 ++++++++++++ drivers/clk/at91/pmc.c | 71 +++++++++++++ drivers/clk/at91/pmc.h | 18 ++++ drivers/clk/at91/sckc.c | 30 ++++++ 17 files changed, 784 insertions(+), 3 deletions(-) create mode 100644 drivers/clk/at91/Kconfig create mode 100644 drivers/clk/at91/Makefile create mode 100644 drivers/clk/at91/clk-generated.c create mode 100644 drivers/clk/at91/clk-h32mx.c create mode 100644 drivers/clk/at91/clk-main.c create mode 100644 drivers/clk/at91/clk-master.c create mode 100644 drivers/clk/at91/clk-peripheral.c create mode 100644 drivers/clk/at91/clk-plla.c create mode 100644 drivers/clk/at91/clk-slow.c create mode 100644 drivers/clk/at91/clk-system.c create mode 100644 drivers/clk/at91/clk-utmi.c create mode 100644 drivers/clk/at91/pmc.c create mode 100644 drivers/clk/at91/pmc.h create mode 100644 drivers/clk/at91/sckc.c diff --git a/arch/arm/mach-at91/include/mach/at91_pmc.h b/arch/arm/mach-at91/include/mach/at91_pmc.h index 680ceb0..2875ff2 100644 --- a/arch/arm/mach-at91/include/mach/at91_pmc.h +++ b/arch/arm/mach-at91/include/mach/at91_pmc.h @@ -149,6 +149,9 @@ typedef struct at91_pmc { #define AT91_PMC_PCR_PID_MASK (0x3f) #define AT91_PMC_PCR_GCKCSS (0x7 << 8) +#define AT91_PMC_PCR_GCKCSS_MASK 0x07 +#define AT91_PMC_PCR_GCKCSS_OFFSET 8 +#define AT91_PMC_PCR_GCKCSS_(x) ((x & 0x07) << 8) #define AT91_PMC_PCR_GCKCSS_SLOW_CLK (0x0 << 8) #define AT91_PMC_PCR_GCKCSS_MAIN_CLK (0x1 << 8) #define AT91_PMC_PCR_GCKCSS_PLLA_CLK (0x2 << 8) @@ -158,8 +161,9 @@ typedef struct at91_pmc { #define AT91_PMC_PCR_CMD_WRITE (0x1 << 12) #define AT91_PMC_PCR_DIV (0x3 << 16) #define AT91_PMC_PCR_GCKDIV (0xff << 20) -#define AT91_PMC_PCR_GCKDIV_(x) (((x) & 0xff) << 20) -#define AT91_PMC_PCR_GCKDIV_OFFSET 20 +#define AT91_PMC_PCR_GCKDIV_MASK 0xff +#define AT91_PMC_PCR_GCKDIV_OFFSET 20 +#define AT91_PMC_PCR_GCKDIV_(x) ((x & 0xff) << 20) #define AT91_PMC_PCR_EN (0x1 << 28) #define AT91_PMC_PCR_GCKEN (0x1 << 29) @@ -243,8 +247,9 @@ typedef struct at91_pmc { #define AT91_PMC_PCK1RDY (1 << 9) /* Programmable Clock 1 */ #define AT91_PMC_PCK2RDY (1 << 10) /* Programmable Clock 2 */ #define AT91_PMC_PCK3RDY (1 << 11) /* Programmable Clock 3 */ +#define AT91_PMC_MOSCSELS BIT(16) /* Main Oscillator Selection Status */ +#define AT91_PMC_MOSCRCS BIT(17) /* 12 MHz RC Oscillator Status */ #define AT91_PMC_GCKRDY (1 << 24) - #define AT91_PMC_PROTKEY 0x504d4301 /* Activation Code */ /* PLL Charge Pump Current Register (PMC_PLLICPR) */ diff --git a/drivers/clk/Kconfig b/drivers/clk/Kconfig index 6eee8eb..3da63c0 100644 --- a/drivers/clk/Kconfig +++ b/drivers/clk/Kconfig @@ -22,5 +22,6 @@ config SPL_CLK source "drivers/clk/uniphier/Kconfig" source "drivers/clk/exynos/Kconfig" +source "drivers/clk/at91/Kconfig" endmenu diff --git a/drivers/clk/Makefile b/drivers/clk/Makefile index f7a8891..863a8d7 100644 --- a/drivers/clk/Makefile +++ b/drivers/clk/Makefile @@ -13,3 +13,4 @@ obj-$(CONFIG_SANDBOX) += clk_sandbox_test.o obj-$(CONFIG_MACH_PIC32) += clk_pic32.o obj-$(CONFIG_CLK_UNIPHIER) += uniphier/ obj-$(CONFIG_CLK_EXYNOS) += exynos/ +obj-$(CONFIG_CLK_AT91) += at91/ diff --git a/drivers/clk/at91/Kconfig b/drivers/clk/at91/Kconfig new file mode 100644 index 0000000..10050d8 --- /dev/null +++ b/drivers/clk/at91/Kconfig @@ -0,0 +1,43 @@ +config CLK_AT91 + bool "AT91 clock drivers" + depends on CLK + help + This option is used to enable the AT91 clock driver. + The driver supports the AT91 clock generator, including + the oscillators and PLLs, such as main clock, slow clock, + PLLA, UTMI PLL.

[U-Boot] [PATCH] tpm: atmel_twi: Make compatible with DM I2C busses
by Mario Six 15 Aug '16

15 Aug '16

Commit 302c5db ("dm: tpm: Add Driver Model support for tpm_atmel_twi driver") converted the Atmel TWI TPM driver itself to driver model, but kept the legacy-style i2c_write/i2c_read calls. Commit 3e7d940 ("dm: tpm: Every TPM drivers should depends on DM_TPM") then made DM_I2C a dependency of the driver, effectively forcing users to turn on CONFIG_DM_I2C_COMPAT to get it to work. This patch adds the necessary dm_i2c_write/dm_i2c_read calls to make the driver compatible with DM, but also keeps the legacy calls in ifdefs, so that the driver is now compatible with both DM and non-DM setups.
