This adds prepare/unprepare/is_prepared functionality to the drivers for
the SI544 and SI514 chips, allowing the clock output to be disabled when
the clock is not in use.

Quoting Mike Looijmans (2018-05-31 07:03:55)
The si544 driver had a rounding problem that using the result of clk_round_rate
may set the clock to yet another rate, for example:
clk_round_rate(19500) = 19499
clk_round_rate(19499) = 19498
(clk, actual_freq);
clk_round_rate(clk, actual_freq) == actual_freq && clk_get_rate(clk) ==
actual_freq

The power-off call is done in a context that must be able to sleep, so
use gpiod_set_value_cansleep instead of the atomic gpiod_set_value call.
This fixes a kernel warning at shutdown when the gpio is controlled
through an IO expander for example.

I'd be interested in use-cases for having nvmem as a module, I cannot think of
any.
I am working on splitting of_get_nvmem_mac_address(), by moving most of its
burden to the nvmem interface. Intend to create this "just
ressed. I think having nvnmem_core
as a module doesn't make much sense anyway, but that's not up to me.
Moving the code from of to nvmem seems weird, but would solve it.
Kind regards,

It's common practice to store MAC addresses for network interfaces into

so this patch adds of_get_nvmem_mac_address() for drive

Call of_get_nvmem_mac_address() to fetch the MAC address from an nvmem
cell, if one is provided in the device tree. This allows the address to
be stored in an I2C EEPROM device for example.
