* serial: bcm283x_mu: Detect disabled serial deviceAlexander Graf2016-09-06-0/+1
| | | | | | | | | | | | | | | | | | | | On the raspberry pi, you can disable the serial port to gain dynamic frequency scaling which can get handy at times. However, in such a configuration the serial controller gets its rx queue filled up with zero bytes which then happily get transmitted on to whoever calls getc() today. This patch adds detection logic for that case by checking whether the RX pin is mapped to GPIO15 and disables the mini uart if it is not mapped properly. That way we can leave the driver enabled in the tree and can determine during runtime whether serial is usable or not, having a single binary that allows for uart and non-uart operation.

* fdt: allow fdtdec_get_addr_size_*() to translate addressesStephen Warren2016-08-12-1/+1
| | | | | | | | | | | | | | | Some code may want to read reg values from DT, but from nodes that aren't associated with DM devices, so using dev_get_addr_index() isn't appropriate. In this case, fdtdec_get_addr_size_*() are the functions to use. However, "translation" (via the chain of ranges properties in parent nodes) may still be desirable. Add a function parameter to request that, and implement it. Update all call sites to default to the original behaviour.

* gpio: Add driver for TI PCF8575 I2C GPIO expanderVignesh R2016-08-08-0/+188
| | | | | | | | | | | | | | | | | | TI's PCF8575 is a 16-bit I2C GPIO expander.The device features a 16-bit quasi-bidirectional I/O ports. Each quasi-bidirectional I/O can be used as an input or output without the use of a data-direction control signal. The I/Os should be high before being used as inputs. Read the device documentation for more details[1]. This driver is based on pcf857x driver available in Linux v4.7 kernel. It supports basic reading and writing of gpio pins.

* dm: gpio: MPC85XX GPIO platform data supportHamish Martin2016-07-11-7/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Define a platform data structure for the MPC85XX GPIO driver to allow use of the driver without device tree. Users should define the GPIO blocks for their platform like this: struct mpc85xx_gpio_plat gpio_blocks[] = { { .addr = 0x130000, .ngpios = 32, }, { .addr = 0x131000, .ngpios = 32, }, }; U_BOOT_DEVICES(my_platform_gpios) = { { "gpio_mpc85xx", &gpio_blocks[0] }, { "gpio_mpc85xx", &gpio_blocks[1] }, }; This is intended to build upon the recent submission of the base MPC85XX driver from Mario Six. We need to use that new driver without dts support and this patch gives us that flexibility. This has been tested on a Freescale T2080 CPU, although only the first GPIO block.

The usual functions of GPIO drivers (setting input/output mode and output value setting) are supported.
