Subject: [PATCH v4 04/11] crypto: ccp: move setting PSP master to earlier in the init
Date: Thu, 8 Jun 2023 06:17:50 -0500	[thread overview]
Message-ID: <20230608111757.32054-5-mario.limonciello@amd.com> (raw)
In-Reply-To: <20230608111757.32054-1-mario.limonciello@amd.com>

Dynamic boost control needs to use platform access symbols
that look for the PSP master as part of initialization.

So move the PSP master before psp_init() so that dynamic boost
control can be initialized properly.

v3->v4:
 * Pick up tag
v2->v3:
 * Clean up master device if psp_init() failed
