2023-07-13spi: pl022: Add chip-select gpio supportLukas Funke1-2/+33
Add support for an optional external chip-select gpio. Signed-off-by: Lukas Funke <lukas.funke@weidmueller.com> Signed-off-by: Stefan Herbrechtsmeier <stefan.herbrechtsmeier@weidmueller.com> Reviewed-by: Jagan Teki <jagan@amarulasolutions.com>
2023-07-13spi: pl022: Remove platform data headerStefan Herbrechtsmeier1-1/+7
Remove the platform data header because its content is only used by the driver. Signed-off-by: Stefan Herbrechtsmeier <stefan.herbrechtsmeier@weidmueller.com> Reviewed-by: Jagan Teki <jagan@amarulasolutions.com>
2023-07-13spi: pl022: Rename flush into pl022_spi_flushStefan Herbrechtsmeier1-3/+3
Rename the flush function into pl022_spi_flush to avoid conflicting types with previous declaration of the function in stdio.h header. Signed-off-by: Stefan Herbrechtsmeier <stefan.herbrechtsmeier@weidmueller.com> Reviewed-by: Jagan Teki <jagan@amarulasolutions.com>

Align the compatible property with the kernel device tree binding [1] by removing the '-spi' suffix.

2021-09-25treewide: Use OF_REAL instead of !OF_PLATDATASimon Glass1-2/+2
Now that we have a 'positive' Kconfig option, use this instead of the negative one, which is harder to understand. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-02-02common: Drop asm/global_data.h from common headerSimon Glass1-0/+1
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2021-01-05dm: Use access methods for dev/uclass private dataSimon Glass1-1/+1
Most drivers use these access methods but a few do not. Update them. In some cases the access is not permitted, so mark those with a FIXME tag for the maintainer to check.

2020-12-14dm: treewide: Rename ofdata_to_platdata() to of_to_plat()Simon Glass1-2/+2
This name is far too long. Rename it to remove the 'data' bits. This makes it consistent with the platdata->plat rename. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-14dm: treewide: Rename dev_get_platdata() to dev_get_plat()Simon Glass1-1/+1
Rename this to be consistent with the change from 'platdata'. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-14dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass1-2/+2
We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass1-2/+2
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-11-27dm: platform_data: spi: s/pl022_spi.h/spi_pl022.hJagan Teki1-1/+1
Rename platform_data include file as spi_pl022.h from pl022_spi.h, this is generic notation used for spi platdata include files. Acked-by: Quentin Schulz <quentin.schulz@bootlin.com> Signed-off-by: Jagan Teki <jagan@amarulasolutions.com>

2018-11-27spi: pl022: Simplify platdata codeJagan Teki1-28/+20
pl022 spi driver support both OF_CONTROL and PLATDATA, this patch is trying to simplify the code that differentiating platdata vs of_control. - Move OF_CONTROL code at one place - Handle clock setup code directly in pl022_spi_ofdata_to_platdata Acked-by: Quentin Schulz <quentin.schulz@bootlin.com> Signed-off-by: Jagan Teki <jagan@amarulasolutions.com>
2018-09-26spi: add support for ARM PL022 SPI controllerQuentin Schulz1-0/+338
This adds support for the ARM PL022 SPI controller for the standard variant (0x00041022) which has a 16bit wide and 8 locations deep TX/RX FIFO. A few parts were borrowed from the Linux kernel driver. Cc: Armando Visconti <armando.visconti@st.com> Cc: Vipin Kumar <vipin.kumar@st.com> Signed-off-by: Quentin Schulz <quentin.schulz@bootlin.com>
