Re: [PATCH v3 1/4] mmc: pic32: Refresh PIC32 MMC driver

Am Dienstag, den 01.09.2020, 02:55 +0000 schrieb John Robertson:

The existing driver is not compatible with the Driver Model.

This patch makes the necessary changes while also removing obsolescent calls/properties as follows:

• fdtdec_* calls replaced with dev_read_* equivalents;
• 'clock-freq-min-max' property replaced by querying the frequency of the source clock 'base_clk';
• The card detect erratum workaround is applied during probe rather than overriding get_cd.

The card detect workaround (Microchip ref. DS80000736E, erratum #15) is not always needed and can be disabled using a vendor specific DT property.

Changes in v3 - address review comments from Daniel Schwierzeck

• Remove <common.h>, DECLARE_GLOBAL_DATA_PTR not required by dev_* API
• Replace dev_read_addr_size() + ioremap() with dev_remap_addr()
