dtoc: Support widening a bool value

2021-08-01T15:05:24+00:00

At present if we see 'ranges' property (with no value) we assume it is a boolean, as per the devicetree spec. But another node may define 'ranges' with a value, forcing us to widen it to an int array. At present this is not supported and causes an error. Fix this and add some test cases.

dtoc: Fix widening an int array to an int

2021-08-01T15:05:24+00:00

An int array can hold a single int so we should not need to do anything in the widening operation. However due to a quirk in the code, an int[3] widened with an int produced an int[4]. Fix this and add a test. Fix a comment typo while we are here. Signed-off-by: Simon Glass Reported-by: Tom Rini

dm: core: Create a struct for device runtime info

2021-03-26T04:03:09+00:00

At present when driver model needs to change a device it simply updates the struct udevice structure. But with of-platdata-inst most of the fields are not modified at runtime. In fact, typically only the flags need to change. For systems running SPL from read-only memory it is convenient to separate out the runtime information, so that the devices don't need to be copied before being used. Create a new udevice_rt table, similar to the existing driver_rt. For now it just holds the flags, although they are not used in this patch. Add a new Kconfig for the driver_rt data, since this is not needed when of-platdata-inst is used. Signed-off-by: Simon Glass Signed-off-by: Simon Glass

sandbox: Create a new sandbox_noinst build

2021-03-26T04:03:09+00:00

Move sandbox_spl over to use OF_PLATDATA_INST. Create a new board to test the case when this is not enabled, since we will be keeping that code around for several months and want to avoid regressions. Skip the dm_test_of_plat_dev() test since driver info is not available for OF_PLATDATA_INST. Signed-off-by: Simon Glass Signed-off-by: Simon Glass

Revert "sandbox: Disable I2C emulators in SPL"

2021-03-26T04:03:08+00:00

With recent changes this can be supported again. Add it back. This reverts commit d85f2c4f2970d0ec2f5f075de734afd11200d153. Signed-off-by: Simon Glass Signed-off-by: Simon Glass

dm: Rename device_get_by_driver_info_idx()

2021-03-26T04:03:08+00:00

This function finds a device by its driver_info index. With of-platdata-inst we do not use driver_info, but instead instantiate udevice records at build-time. However the semantics of using the function are the same in each case: the caller provides an index and gets back a device. So rename the function to device_get_by_ofplat_idx(), so that it can be used for both situations. The caller does not really need to worry about the details.

dm: core: Drop device_get_by_driver_info()

2021-03-26T04:03:08+00:00

This function is now only used in a test. Drop it. Also drop DM_DRVINFO_GET() which was the only purpose for having the function. Signed-off-by: Simon Glass Signed-off-by: Simon Glass

Create a version of this driver for sandbox so that it can use the of-platdata struct. Signed-off-by: Simon Glass Signed-off-by: Simon Glass

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42+00:00

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 at all, so remove that include. Signed-off-by: Simon Glass Signed-off-by: Tom Rini

sandbox: Disable I2C emulators in SPL

2021-01-30T21:25:41+00:00

These cannot work with of-platdata since they currently need the devicetree at runtime. Disable the emulators and the sandbox I2C driver that needs them. We can enable these later, if needed for testing. Switch the of_plat_parent test over to use a simple bus instead. Signed-off-by: Simon Glass Reviewed-by: Heiko Schocher
