2012-10-15mx5 clocks: Fix get_lp_apm()Benoît Thébaudeau
If CCM.CCSR.lp_apm is set, the lp_apm clock is not necessarily 32768 Hz x 1024. In that case: - on i.MX51, this clock comes from the output of the FPM, - on i.MX53, this clock comes from the output of PLL4. This patch fixes the code accordingly.

2012-10-15mx5 clocks: Add and use CCSR definitionsBenoît Thébaudeau
This fixes config_pll_clk(), which used 0x20 instead of 0x200 for PLL4_CLOCK. Signed-off-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com> Cc: Stefano Babic <sbabic@denx.de>
2012-10-15mx51: Fix USB PHY clocksBenoît Thébaudeau
The i.MX51 has a single USB PHY clock, while the i.MX53 has two. These 3 clocks have different clock gate control bit-fields. The existing code was correct only for i.MX53, so this patch fixes the i.MX51 use case.

2012-10-15mx5: Fix clock gate valuesBenoît Thébaudeau
The clock gate values are 2-bit bit-fields. Hence, setting or clearing only one of these bits like what was done is wrong and can lead to unpredictable behavior depending on the original value of these bit-fields.

2012-10-15mx5 clocks: CleanupBenoît Thébaudeau
Clean up the i.MX5 clock driver: - Use readl() and writel() instead of their __raw_ counterparts. - Use the clr/setbits_le32() family of macros rather than expanding code. - Use accessor macros for bit-fields instead of _MASK and _OFFSET.

2012-10-15tegra20: rework UART GPIO handlingLucas Stach
Rename board provided gpio_config_uart() to gpio_early_init_uart() as it does the same thing as the equally called function provided by the uart-switch code. This allows to simply call this function in early board init whether or not we are building with CONFIG_UART_SWITCH defined. Also provide a weak symbol for this function, to avoid the need to provide this function for boards that don't need any fixup. This patch supersedes the earlier posted "tegra: convert gpio_config_uart to weak symbol".

2012-10-15tegra20: add clock_set_pllout functionLucas Stach
Common practice on Tegra 2 boards is to use the pllp_out4 FO to generate the ULPI reference clock. For this to work we have to override the default hardware generated output divider.

2012-10-15Tegra20: Move some include files to arch-tegra for sharing with Tegra30Tom Warren
The move is pretty straight-forward. ap20.h and tegra20.h were renamed to ap.h and tegra.h. Some files remain in arch-tegra20 but 'include' a file in 'arch-tegra' with #defines & structs that will be common between T20 and T30 HW. HW-specific #defines, etc. stay in the 'arch-tegra20' 'root' file. All boards build OK w/MAKEALL -s tegra20. Checkpatch.pl runs clean. Seaboard works OK.

2012-10-15Tegra20: Move some code files to common directories for upcoming Tegra30 ↵Tom Warren
patches. Move files that are going to be common between T20 and T30 into 'tegra-common' subdirs in AVP (arm720t), CPU (armv7), and shared (arch/arm/cpu/.) areas. Any files that are left behind in '/tegra20' will be copied to '/tegra30' subdirs and modified for that SoC. The 'common' files should need only minor changes. Include files (arch/arm/include/asm/arch-tegra/tegra20) will be done in a follow-on patch. Builds fine w/MAKEALL -s tegra20. Checkpatch.pl is clean. Signed-off-by: Tom Warren <twarren@nvidia.com>
2012-10-15tegra20: add USB ULPI init codeLucas Stach
This adds the required code to set up a ULPI USB port. It is mostly a port of the Linux ULPI setup code with some tweaks added for more correctness, discovered along the way of debugging this. To use this both CONFIG_USB_ULPI and CONFIG_USB_ULPI_VIEWPORT have to be set in the board configuration file.

2012-10-15usb: ehci: rework to take advantage of new lowlevel interfaceLucas Stach
Kill off ehci-core.h It was used to specify some static controller data. To support more than one controller being active at any time we have to carry the controller data ourselfes. Change the ehci interface accordingly. NOTE: OMAP implemented the ehci stuff a bit backwards and should be fixed to do the same thing as other platforms. But the change for now is at least compile clean. Signed-off-by: Lucas Stach <dev@lynxeye.de> Reviewed-by: Marek Vasut <marex@denx.de>

Rework the emulation of serial console via JTAG from simple ad-hoc implementation of serial port routines to CONFIG_SERIAL_MULTI and enable CONFIG_SERIAL_MULTI unconditionally for blackfin. In order for the JTAG serial console to take precedence over all other serial ports available in system, implement override for default_serial_console call returning this JTAG serial console.

2012-10-15serial: mpc512x: Move serial registration from serial_initialize()Marek Vasut
Move the registration of serialN_device ports from default serial_initialize() into driver specific function called from serial_initialize(). This slims down the serial_initialize() call to a bare tracker of all possible serial port registration routines in U-Boot. The newly implemented mpc512x_serial_initialize() function, which is implemented inside of the mpc512x serial driver allows encapsulation of serialN_device within the mpc512x serial driver itself. Also, remove the exports of serialN_device from include/serial.h as they are no longer needed.
