🌸 Members 🌸

• l3_perm_bit — this is the bit shift for L3_PM_*_PERMISSION_*. like, the shift, okay? it tells you where in the permission situation this bit lives 🧚
• l4_fw_region — the L4 firewall region ID. which region? this one. ID included 💖
• l4_prot_group — the L4 protection group ID. your lil protection squad, tagged and numbered 🎀
• flags — the flags! and lowkey the manpage says (see omap_hwmod_omap2_firewall.flags macros above), so like… go look above, the macros are literally right there, iykyk 🙈
