From: Kory Maincent (Dent Project) Date: Wed, 17 Apr 2024 14:39:57 +0000 (+0200) Subject: net: pse-pd: Add support for setup_pi_matrix callback X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=29e28d1d7a16a3f6dba55c1df5cc6e0f9edf3017;p=linux.git net: pse-pd: Add support for setup_pi_matrix callback Implement setup_pi_matrix callback to configure the PSE PI matrix. This functionality is invoked before registering the PSE and following the core parsing of the pse_pis devicetree subnode.
