/*
|
||||
* cpld-gpio-bus.c: provides support for the CPLD GPIO bus found on some LaCie |
||||
* boards (as the 2Big/5Big Network v2 and the 2Big NAS). This parallel GPIO |
||||
* bus exposes two registers (address and data). Each of this register is made |
||||
* up of several dedicated GPIOs. An extra GPIO is used to notify the CPLD that |
||||
* the registers have been updated. |
||||
* |
||||
* Mostly this bus is used to configure the LEDs on LaCie boards. |

- samsung,exynos5250-dwmmc: for exynos5250 platforms |
||||
|
||||
- reg: physical base address of the controller and length of memory mapped |
||||
region. |
||||
|
||||
- interrupts: The interrupt number to the cpu. |
||||
|
||||
Required Board Specific Properties: |
||||
|
||||
- #address-cells: should be 1. |
||||
- #size-cells: should be 0. |
||||
- samsung,bus-width: The width of the bus used to interface the devices |
||||
supported by DWC_mobile_storage (SD-MMC/EMMC/SDIO). |
||||
. Typically the bus width is 4 or 8. |
||||
- samsung,timing: The timing values to be written into the |
||||
Drv/sample clock selection register of corresponding channel. |
||||
. It is comprised of 3 values corresponding to the 3 fileds |
||||
'SelClk_sample', 'SelClk_drv' and 'DIVRATIO' of CLKSEL register. |
||||
. SelClk_sample: Select sample clock among 8 shifted clocks. |
||||
. SelClk_drv: Select drv clock among 8 shifted clocks. |
||||
. DIVRATIO: Clock Divide ratio select. |
||||
. The above 3 values are used by the clock phase shifter. |
||||
|
||||
Example: |
||||
|
||||
mmc@12200000 { |
||||
samsung,bus-width = <8>; |
||||
samsung,timing = <1 3 3>; |
||||
samsung,removable = <1>; |
||||
} |
||||
In the above example, |
||||
. The bus width is 8 |
||||
. Timing is comprised of 3 values as explained below |
||||
1 - SelClk_sample |
||||
3 - SelClk_drv |
||||
3 - DIVRATIO |
||||
. The 'removable' flag indicates whether the the particilar device |
||||
cannot be removed (always present) or it is a removable device. |
||||
1 - Indicates that the device is removable. |
||||
0 - Indicates that the device cannot be removed. |
