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.

There were two little corrections in my last reply (missing semicolon + missing
.platdata_auto_alloc_size); if you could add those, that would be great.

Is this a v2/v3 patch? If so, can you please resend it with the version number?

Define a platform data structure for the MPC85XX GPIO driver to allow

blocks for their platform like this:
struct mpc85xx_gpio_plat gpio_blocks[] = {
{
.addr = 0x130000,

},
};
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

here, otherwise the data structure is not allocated properly.
