Subject: [PATCH v2 0/3] at91: Remove of_platform_default_populate() calls
Date: Thu, 20 Nov 2025 15:37:49 -0600	[thread overview]
Message-ID: <20251120-at91-probe-v2-0-8c8592f02e8e@kernel.org> (raw)

This is another attempt at removing of_platform_default_populate() calls 
on at91 platforms. The last attempts were in 2018[1] and 2023[2]. The 
problems reported are PM and NAND failures. Both of these depend on SRAM 
pool which doesn't have any fw_devlink tracking. Also, the PM code is 
not a driver, so fw_devlink wouldn't help. For the NAND driver, we can 
simply defer probe. For the PM init, we can move it to the .late_init 
hook.
