| * ARM/ASoC: omap-mcbsp: Remove CLKR/FSR mux configuration codePeter Ujfalusi2012-08-222-78/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the feature to configure the CLKR/FSR mux on McBSP port with 6pin configuration. When moving to devicetree these callback can no longer be used in a clean way anymore. If a board require to change the 6pin port to work in 4pin setup it needs to set up the mux in the board file. For OMAP2/3: u32 devconf0; /* McBSP1 CLKR/FSR signal to be connected to CLKX/FSX pin */ devconf0 = omap_ctrl_readl(OMAP2_CONTROL_DEVCONF0); devconf0 |= OMAP2_MCBSP1_CLKR_MASK | OMAP2_MCBSP1_FSR_MASK; omap_ctrl_writel(devconf0, OMAP2_CONTROL_DEVCONF0); For OMAP4: u32 mcbsp_pad; /* McBSP4 CLKR/FSR signal to be connected to CLKX/FSX pin */ mcbsp_pad = omap4_ctrl_pad_readl(OMAP2_CONTROL_DEVCONF0); mcbsp_pad |= ((1 << 31) | (1 << 30)); omap4_ctrl_pad_writel(mcbsp_pad, OMAP2_CONTROL_DEVCONF0); In case when the kernel is booted with DT blob the pinctrl-single will be provided as soon as it is enabled on the platform.

In the P2M tree however the space for those leafs must be reserved - as such we use extend_brk. We reserve 8MB of _brk space, which means we can fit over 1048576 PFNs - which is more than we should ever need.

In compat mode however the passed in address will be modified with compat_ptr() which masks out the most significant bit. The result is that in native 31 bit mode each mmap request (with MAP_FIXED) will fail where the most significat bit is set, while in compat mode it may succeed. This odd behaviour was introduced with d3815898 "[S390] mmap: add missing compat_ptr conversion to both mmap compat syscalls". To restore a consistent behaviour accross native and compat mode this patch functionally reverts the above mentioned commit.

The line is automatically deasserted once all data has been read via I2C. Hence, the driver has to monitor the GPIO line and cannot simply rely on the interrupt handler reception. In the current implementation of the driver, irq_to_gpio() is used to determine the GPIO number from the i2c_client's IRQ value. As irq_to_gpio() is not available on all platforms, this patch changes this and makes the driver ignore the passed in IRQ. Instead, a GPIO is added to the platform_data struct and gpio_to_irq is used to derive the IRQ from that GPIO. If this fails, bail out. The driver is only able to work in environments where the touchscreen GPIO can be mapped to an IRQ.

However, it appears that I only tested it when booting using board files, not when booting using device tree. This change fixes two problems with regulators when booting using device tree: 1) That patch only created the vdd_sys regulator when booting using a board file. Since this is the root of the whole regulator tree, this caused no regulators to successfully initialize when booting using device tree. The registration of vdd_sys is moved to fix this. 2) When booting use DT, the regulator core sets has_full_constraints, which in turn causes the core to turn off any regulators not marked as always on. Some of the affected regulators are required for basic system operation. To solve this, add always on constraints to all relevant regulators. This doesn't affect booting using a board file since nothing sets has_full_constraints in that case. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

There's not much point in having defconfigs change it - that would just be pure noise in the config files." the CONFIG_DEFAULT_MMAP_MIN_ADDR can be removed from the defconfig altogether.
