* x86: apl: Adjust how the UART gets its platform dataSimon Glass2021-01-051-19/+24
| | | | | | | | | | | | At present this driver calls malloc() to start a new platform data structure, fills it in and tells driver model to use it. We want to avoid malloc, particularly with the new version of of-platdata. Create a new struct which encompasses both the dtd struct and the ns16550 one, to avoid this. Unfortunately we must copy the data into the right place for the ns16550 driver. Add some comments about this. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: apl: Reduce size for TPLSimon Glass2021-01-051-1/+3
| | | | | | | | | | Update various drivers to use of_match_ptr() and to avoid including debug strings in TPL. Omit the WiFi driver entirely, since it is not used in TPL. This reduces the TPL binary size by about 608 bytes. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Use access methods for dev/uclass private dataSimon Glass2021-01-051-1/+2
| | | | | | | | | | | 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.

* serial: Update NS16550_t and struct NS16550Simon Glass2021-01-051-1/+1
| | | | | | | | | | | Typedefs should not be used in U-Boot and structs should be lower case. Update the code to use struct ns16550 consistently. Put a header guard on the file while we are here.

* dm: treewide: Rename ..._platdata variables to just ..._platSimon Glass2020-12-131-4/+4
| | | | | | | Try to maintain some consistency between these variables by using _plat as a suffix for them. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: treewide: Rename ofdata_to_platdata() to of_to_plat()Simon Glass2020-12-131-4/+4
| | | | | | | 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>
* dm: treewide: Rename dev_get_platdata() to dev_get_plat()Simon Glass2020-12-131-2/+2
| | | | | | Rename this to be consistent with the change from 'platdata'. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass2020-12-131-3/+3
| | | | | | | | | | 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>
* dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass2020-12-131-2/+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>
* x86: Fix up driver names to avoid dtoc warningsSimon Glass2020-11-051-1/+1
| | | | | | | | | | | | At present there are a lot of dtoc warnings reported when building chromebook_coral, of the form: WARNING: the driver intel_apl_lpc was not found in the driver list Correct these by using driver names that matches their compatible string.

* dm: core: Create a new header file for 'compat' featuresSimon Glass2020-02-051-0/+1
| | | | | | | | | | | | At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

* x86: apl: Add UART driverSimon Glass2019-12-151-0/+133
Add a driver for the Apollo Lake UART. It uses the standard ns16550 device but also sets up the input clock with LPSS and supports configuration via of-platdata. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
