-/* Procedure of MT753x Internal Register Access
- *
- * 1. Internal Register Address
- *
- * The MT753x has a 16-bit register address and each register is 32-bit.
- * This means the lowest two bits are not used as the register address is
- * 4-byte aligned.
- *
- * Rest of the valid bits are divided into two parts:
- * Bit 15..6 is the Page address
- * Bit 5..2 is the low address
- *
- * -------------------------------------------------------------------
- * | 15 14 13 12 11 10 9 8 7 6 | 5 4 3 2 | 1 0 |
- * |----------------------------------------|---------------|--------|
- * | Page Address | Address | Unused |
- * -------------------------------------------------------------------
- *
- * 2. MDIO access timing
- *
- * The MT753x uses the following MDIO timing for a single register read
- *
- * Phase 1: Write Page Address
- * -------------------------------------------------------------------
- * | ST | OP | PHY_ADDR | TYPE | RSVD | TA | RSVD | PAGE_ADDR |
- * -------------------------------------------------------------------
- * | 01 | 01 | 11111 | 1 | 1111 | xx | 00000 | REG_ADDR[15..6] |
- * -------------------------------------------------------------------
- *
- * Phase 2: Write low Address & Read low word
- * -------------------------------------------------------------------
- * | ST | OP | PHY_ADDR | TYPE | LOW_ADDR | TA | DATA |
- * -------------------------------------------------------------------
- * | 01 | 10 | 11111 | 0 | REG_ADDR[5..2] | xx | DATA[15..0] |
- * -------------------------------------------------------------------
- *
- * Phase 3: Read high word
- * -------------------------------------------------------------------
- * | ST | OP | PHY_ADDR | TYPE | RSVD | TA | DATA |
- * -------------------------------------------------------------------
- * | 01 | 10 | 11111 | 1 | 0000 | xx | DATA[31..16] |
- * -------------------------------------------------------------------
- *
- * The MT753x uses the following MDIO timing for a single register write
- *
- * Phase 1: Write Page Address (The same as read)
- *
- * Phase 2: Write low Address and low word
- * -------------------------------------------------------------------
- * | ST | OP | PHY_ADDR | TYPE | LOW_ADDR | TA | DATA |
- * -------------------------------------------------------------------
- * | 01 | 01 | 11111 | 0 | REG_ADDR[5..2] | xx | DATA[15..0] |
- * -------------------------------------------------------------------
- *
- * Phase 3: write high word
- * -------------------------------------------------------------------
- * | ST | OP | PHY_ADDR | TYPE | RSVD | TA | DATA |
- * -------------------------------------------------------------------
- * | 01 | 01 | 11111 | 1 | 0000 | xx | DATA[31..16] |
- * -------------------------------------------------------------------
