Subject: [PATCH] ARM: at91: Kconfig: implement PIT64B selection
Date: Wed, 9 Mar 2022 12:08:02 +0200 [thread overview]
Message-ID: <20220309100802.3610259-1-claudiu.beznea@microchip.com> (raw)
Implement PIT64B selection thus it will be available for the necessary
targets (at the moment SAM9X60 and SAMA7G5) w/o the necessity to
specify it via defconfig. With this the current CONFIG_TIMER_OF
dependency of PIT64B driver could be removed. Along with changes
on AT91 Kconfig removed CONFIG_MICROCHIP_PIT64B from defconfigs.
