imx: dma: correct MXS_DMA_ALIGNMENT

2015-05-26T12:14:49Z

We should not hardcode MXS_DMA_ALIGNMENT to 32, since we can not guarantee that socs' cache line size is 32 bytes. If on chips whose cache line size is 64 bytes, error occurs: " NAND: ERROR: v7_dcache_inval_range - start address is not aligned - 0xbdf1d1a0 ERROR: v7_dcache_inval_range - stop address is not aligned - 0xbdf1f4a0 ERROR: v7_dcache_inval_range - start address is not aligned - 0xbdf1d1a0 " Align MXS_DMA_ALIGNMENT with ARCH_DMA_MINALIGN whose value is same to CONFIG_SYS_CACHELINE_SIZE if CONFIG_SYS_CACHELINE_SIZE defined.

i2c: mxc: refactor i2c driver and support dm

2015-05-15T00:49:36Z

1. Introduce a new structure `struct mxc_i2c_bus`, this structure will used for non-DM and DM. 2. Remove `struct mxc_i2c_regs` structure, but use register offset to access registers based on `base` entry of `struct mxc_i2c_bus`. 3. Remove most `#ifdef I2C_QUIRK_REG`. Using driver_data to contain platform flags. A new flag is introduced, I2C_QUIRK_FLAG. 4. Most functions use `struct mxc_i2c_bus` as one of the parameters. Make most functions common to DM and non-DM, try to avoid duplicated code. 5. Support DM, but pinctrl is not included. Pinmux setting is still set by setup_i2c, but we do not need bus_i2c_init for DM. 6. struct i2c_parms and struct sram_data are removed. 7. Remove bus_i2c_read bus_i2c_write prototype in header file. The frist paramter of bus_i2c_init is modified to i2c index. Add new prototype i2c_idle_bus and force_bus_idle. Since bus_i2c_init is not good for DM I2C and pinctrl is missed, we use a weak function for i2c_idle_bus. Board file take the responsibility to implement this function, like this: " int i2c_idle_bus(struct mxc_i2c_bus *i2c_bus) { if (i2c_bus->index == 0) force_bus_idle(i2c_pads_info0); else if (i2c_bus->index == 1) force_bus_idle(i2c_pads_info1); else xxxxxx } " 8. Introduce a weak function, enable_i2c_clk 9. Tested on an i.MX7 platform.

video, ipu: make ldb clock frequency overwritable through board code

2015-04-20T07:36:59Z

the ldb clock can be setup in board code (for example set through PLL5). Update the ldb_clock rate also through board code. This should be removed, if a clock framework is availiable. Signed-off-by: Heiko Schocher Tested-by: Eric Nelson

imx: mx6 sabreauto: Add board support for USB EHCI

2014-11-03T10:21:49Z

On mx6 sabreauto board, there are two USB ports: 0: OTG 1: HOST The EHCI driver is enabled for this board, but the IOMUX and VBUS power control is not implemented, which cause both USB port failed to work. This patch fix the problem by adding the board support codes. Since the power control uses the GPIO pin from port expander MAX7310, the PCA953X driver is enabled for accessing the MAX7310. The ID pin of OTG Port needs to configure the GPR1 bit 13 for selecting its daisy chain. Add a new function "imx_iomux_set_gpr_register" to handle GPR register setting. Signed-off-by: Ye.Li
