media: ipu3-cio2: Drop useless assignments

2020-09-10T12:19:47Z

There are assignments inside the functions which are useless. Drop them for good. Signed-off-by: Andy Shevchenko Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: ipu3-cio2: Drop bogus check and error message

2020-09-10T12:19:24Z

pcim_iomap_table() won't fail if previous pcim_iomap_regions() hasn't. Since we check pcim_iomap_regions() for failure the check close to pcim_iomap_table() is bogus and not needed. Signed-off-by: Andy Shevchenko Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: ipu3-cio2: Get rid of pci_set_master() duplication

2020-09-10T12:19:02Z

It's unclear why driver repeats the code from PCI core. Drop it for good. Signed-off-by: Andy Shevchenko Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: ipu3-cio2: Use readl_poll_timeout() helper

2020-09-10T12:18:35Z

We may use special helper macro to poll IO till condition or timeout occurs. Signed-off-by: Andy Shevchenko Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: ipu3-cio2: Replace infinite loop by one with clear exit condition

2020-09-10T12:13:30Z

Refactor cio2_buffer_done() to get rid of infinite loop by replacing it by one with clear exit condition. This change also allows to check for an error ahead. Signed-off-by: Andy Shevchenko Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: ipu3-cio2: Use macros from pfn.h

2020-09-10T12:12:56Z

There are few nice macros in pfn.h, some of which we may use here. Signed-off-by: Andy Shevchenko Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: ipu2-cio2: Replace custom definition with PAGE_SIZE

2020-09-10T12:12:14Z

It's quite unlikely that another page size will be supported, but in any case there is still an inconsistency between custom page size definition and generic macros used in the driver. Switch over to the generic PAGE_SIZE for sake of the consistency. Signed-off-by: Andy Shevchenko Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: ipu3-cio2: Introduce CIO2_LOP_ENTRIES constant

2020-09-10T12:11:37Z

This constant is used in several places in the code, define it for better maintenance. Signed-off-by: Andy Shevchenko Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: ipu3-cio2: Simplify cleanup code

2020-09-10T12:10:27Z

The code looks more nicer if we use: while (i--) instead: for (i = i - 1; i >= 0; i--) This would also allow making 'i' unsigned again. Signed-off-by: Andy Shevchenko Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab
