regulator: output current-limit for all regulators in summary
Voltage regulators can have (unregulated) current limits too, so we should probably output both voltage and current for all regulators. Holding the rdev->mutex actually conflicts with _regulator_get_current_limit but also is not really necessary, as the global regulator_list_mutex already protects us from the regulator vanishing while we go through the list. On the rk3288-firefly the summary now looks like: regulator use open bypass voltage current min max ------------------------------------------------------------------------------- vcc_sys 0 12 0 5000mV 0mA 5000mV 5000mV vcc_lan 1 1 0 3300mV 0mA 3300mV 3300mV ff290000.ethernet 0mV 0mV vcca_33 0 0 0 3300mV 0mA 3300mV 3300mV vcca_18 0 0 0 1800mV 0mA 1800mV 1800mV vdd10_lcd 0 0 0 1000mV 0mA 1000mV 1000mV [...] Suggested-by: Mark Brown <broonie@kernel.org> Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Mark Brown <broonie@kernel.org>
