mmc: core: Move public functions from host.h to private headers

2017-02-13T12:20:25+00:00

A significant amount of functions are available through the public mmc
host.h header file. Let's slim down this public mmc interface, as to
prevent users from abusing it, by moving some of the functions to private
mmc host.h header file.

This change concentrates on moving the functions into private mmc headers,
following changes may continue with additional clean-ups.

mmc: core: Move public functions from card.h to private headers

A significant amount of functions and other definitions are available

interface, as to prevent users from abusing it, by moving some of the
functions/definitions to private mmc header files.

mmc: debugfs: remove BUG_ON from mmc_ext_csd_open

2016-12-05T09:31:09+00:00

Return error value for file_operations callback instead
of triggering BUG_ON which is meaningless. Personally I
don't believe n != EXT_CSD_STR_LEN could happen. Anyway,
propagate the error to the caller.

Clock frequency values written to an mmc host should not be less than
the minimum clock frequency which the mmc host supports.

mmc: core: Remove MMC_CLKGATE

2015-10-26T15:00:09+00:00

MMC_CLKGATE was once invented to save power by gating the bus clock at
request inactivity. At that time it served its purpose. The modern way to
deal with power saving for these scenarios, is by using runtime PM.

Nowadays, several host drivers have deployed runtime PM, but for those
that haven't and which still cares power saving at request inactivity,
it's certainly time to deploy runtime PM as it has been around for several
years now.

To simplify code to mmc core and thus decrease maintenance efforts, this
patch removes all code related to MMC_CLKGATE.

mmc: core: Use mmc_get_ext_csd() instead of mmc_send_ext_csd()

2014-11-10T11:40:44+00:00

By using mmc_get_ext_csd() in favor of mmc_send_ext_csd, we decrease
code duplication.
